UAV hyperspectral enables precise crop positioning

Hyperspectral remote sensing is short for Hyperspectral Remote Sensing. It is a technology to obtain many very narrow spectral continuous image data in the visible, near-infrared, mid-infrared and thermal infrared bands of the electromagnetic spectrum.

 In recent years, due to more and more investment in scientific research and production forces, drone research and production has accelerated, and the continuous development and innovation of the consumer market has also made drones more and more known to more and more industries Approved. As a flying platform, drones can be equipped with a variety of equipment and applied to various industries, which also determines that it has high applicability to applications in various industries.

 Regardless of the lack of rural labor or the guidance of land intensive policies, agricultural development has higher requirements for further mechanization. Therefore, market supply and demand bridges, and "drone application to agriculture" has become the focus of business and market integration.

 After a period of market practice testing, the application of drone agriculture to the prevention of pests and diseases has been well known to many people, and plant protection drones have also been called "spray drones" by more people. However, the application of drones to plant protection is obviously not limited to pesticide spraying. What other applications does it have? Next we will talk about another specific application in agriculture-agricultural monitoring.

 Agricultural monitoring mainly includes: monitoring of pests and diseases, monitoring of irrigation conditions, and monitoring of crop growth. In addition, after a disaster occurs, it can also be used to evaluate the state of the disaster.

 When the drone is used for monitoring, the drone is equipped with hyperspectral remote sensing (spectral camera) equipment, and uses spatial information technology mainly based on remote sensing technology-through aerial photography of large areas of farmland and land, and learns from shooting data, etc. Crop growth, irrigation in the process of crop growth management, even diseases and insect pests and bacterial invasion that cannot be detected by the naked eye, especially for the management of large plots, UAV remote sensing monitoring can perform a series of monitoring in real time and efficiently to facilitate farmland management For accurate management.

 Hyperspectral remote sensing has the characteristics of high spectral resolution, narrow band range, unified spectrum, and continuous imaging. It can distinguish the nuances of the ground feature spectrum and detect information that other wide-band remote sensing cannot detect.

Precision agriculture technology is just getting started in the U.S.

In China, the market application of autonomous driving is still in the early stages of development, and it only exists in a small amount in large areas such as Northeast and Xinjiang. Variable technology is still in the research and development and promotion stage. In contrast to the situation in China, the birthplace of precision agriculture, the United States, autonomous driving and variable technology applications have reached a high level. So what is the specific development of the United States?

 With reference to Purdue University's investigation on the application of precision agriculture in the United States, the development level of precision agriculture-related technologies such as autonomous driving, drones, and variable technologies was speculated.

 Since 2000, Purdue University has started to investigate the application of precision agriculture-related technologies in the United States, from 2011 to biennial. In August 2015, Purdue University released the results of a recent survey. The survey results show that this survey sent 2,500 survey questionnaires to agricultural distributors and recovered 261. The survey targeted agricultural distributors, and thus radiated all the farms and individuals served by the distributors. The small sample obtained the production situation of the larger arable land area in the United States.

 In addition, the survey results show the application of precision agriculture-related technologies including GPS navigation, autonomous driving, variable technology, and drones, as well as development trends since 2000. The autonomous driving market is mature Figure 1 Application of precision agriculture-related technologies in 2015 From the application of precision agriculture-related technologies in 2015 (Figure 1), it can be seen that among the technologies of precision agriculture, autonomous driving is the most widely used, reaching 83%. It can be seen that autonomous driving technology is quite mature in the United States and has formed a stable market.

 In the current market, there are already many companies producing autonomous driving products, including John Deere, Tianbao, Topcon Precision Agriculture and other companies that our robots know more about. In addition, there are companies such as TeeJet (Tejet, which has entered the Chinese market), AgLeaderTechonologies and Raven. And, unlike the Chinese market that has just started in this area, the US's autonomous driving products have been updated for several generations.

 For example, the John Deere Green Star display has been improved to the 3rd generation in 2013, allowing drivers to switch between 4 guide lines arbitrarily; AgLeaderTechnologies has updated the software of its GeoSteer system to 4.0, which can realize the Switch overlaid maps, define routes and issue warnings when approaching a predetermined route.

 In short, after more than 10 years of development in the United States, autonomous driving has made great progress in reliability, accuracy, and convenience. The drone agriculture application has suddenly risen. Figure 3 Annual Trends of Precision Agriculture Site-Specific Technology The sudden emergence of drone applications in agriculture is the most prominent phenomenon in precision agriculture in the United States in 2015. It can be seen from the precision agriculture site that 2015 is the first year of the application of drones in precision agriculture, and once put on the market, more farmers (16%) use it. It can be seen how hot UAV agricultural applications are in the United States.

I don't know these questions, you dare to talk about agricultural drones.

In August of this year, Lei Feng.com will hold a grand conference on artificial intelligence and robot innovation with unprecedented global influence in Shenzhen. At that time, Lei Feng.com will release the list of “Artificial Intelligence & Robot Top25 Innovative Enterprise List”. At present, we are visiting companies related to artificial intelligence and robotics to screen the list of companies that have finally entered the list.

As a senior practitioner in the industry, Pan Haiyang, the founder of the Green Guardian agricultural drone, has been in the industry for several years. Previously, Lei Feng.com had interviewed Pan Haiyuan around the topic of Green Guardian agricultural drones. For this market, Pan Haiyang believes that “there is a market cycle of about 20-30 years, and it is a good opportunity to make this market a good one.” ". So, what kind of industry background does the agricultural drone market face? What are the points of attention for drone manufacturers who want to deepen this market? In this hard-opening open class, Pan Haiyang will share content around the theme of “How Agricultural Drones Land on the Field”. The following is the content of the open class:

(1) Why did you enter this market at the beginning?

Most of our team is not from the agricultural profession, but most of them are IT men, engage in chips, engage in algorithms, engage in automatic control, engage in machinery, engage in aircraft... Only a small part of agriculture is engaged, so why choose agriculture What about the machine field? At the time, we left the listed company and took a break. When we were looking for something to do, we set ourselves a goal, do something interesting and meaningful, and then accidentally crash into agriculture and information technology. The field of integration, the field of agricultural intelligent equipment, I told the team's partners at the time, we are doing this, optimistic about the opportunities for cross-border development in the next 20 years, instead of following the "Huaqiang North". Before entering the agricultural drone market, we made a deep analysis of the large agricultural market and summarized four trends of modern agricultural development, namely, “changes in land farming practices, changes in the structure of agricultural population, and changes in technological systems. And the changes in the market-oriented model "is precisely to understand the development trend of these four major aspects, we only recognize the agricultural drone market is promising.

 First, changes in land farming practices

 From the collective farming in the form of communes, to the contracting system of individual methods, to the intensive cooperative system, we can see that the trend is evolving in the direction of specialization and scale.

 Second, it is the structural change of the agricultural population.

 Now the main force of rural farming is 60, 50, even a few 40, 70 after 80, basically settled in the city, after 90, after 00, basically do not catch cold, it brings a problem, the older generation of farmers Who will come to farm after retirement? What kind of technical system is used to support agricultural production? Therefore, when young and middle-aged people return to the countryside to engage in agricultural production with their knowledge and culture, they will inevitably bring about technological progress and change. This is the impact of changes in the structure of the agricultural population.

 Third, changes in the technology development system

 In the 30 years of reform and opening up, the technological progress in various fields of various industries has advanced by leaps and bounds. However, the systematic advancement of agricultural technology as the primary industry has only begun to surge in recent years. When communicating with peers, this is called technology spillover effect. In terms of information technology, the performance of the processor is improved, and the development of software technology, after reaching a certain technology platform, will definitely overflow the technology of agriculture, and even include management technologies such as lean production and process control. Tool method. This trend will become more and more obvious, and the impact on the entire agricultural production system can be said to be unprecedented.

 Fourth, the impact of new market-oriented economy on agricultural production methods

 In the Internet+ era, the market economy and various business models have had a huge impact on agricultural production methods, including rural e-commerce, agricultural e-commerce, and rural Internet finance.

 In the context of the above four aspects, we believe that the technical system of agricultural production must be driven by varieties in the future, and varieties or “seedlings” are like integrated circuits in the information industry. In order to more effectively exert the quality or yield advantage of the variety, it is necessary to ensure that the production process of the variety is efficient, correct and as unbiased as possible for the production factors such as “people, machine, material, law, and ring”, and there must be a complete set of technical methods. And standard processes, such as packaging of important production materials such as medicines and fertilizers, supplemented by standardized operation instructions, to ensure that the introduction and trial and error costs are as low as possible when the varieties are promoted. This is a kind of “turnkey” solution. Program.

 (2) As an important mechanized equipment in the agricultural market, how do you view the future development trend of agricultural drones?

 We predict that the high-tech integrated agricultural intelligent equipment represented by agricultural drones will develop toward the trend of “small, personalized, intelligent and systematic (ie, solution)”.

 Miniaturization is determined by the diversity of crop distribution, the degree of land concentration and the rapid upgrading of the aforementioned varieties. It is subject to the limitations of agricultural infrastructure and the main mode of agricultural operation is the planting mode with a land size of several hundred mu, except in Xinjiang and Northeast China. Outside the large farms based on the farmland system and the construction corps, more needs are needed to facilitate rapid deployment, with less investment and high output of small machinery.

 Secondly, due to the diversity of planting methods and the systematic nature of the supporting technical methods, various crops or even different crops of different crops or different regions may have great differences in planting supporting technology. At this time, due to With less-input miniaturized machinery, the finished machine or modular replaceable parts will come into being.

 Then comes the intelligence. Just now we mentioned the spillover effect of information technology and other fields on the technology of agriculture. An important trend is to be intelligent. The farmer jumped directly from the 50s and 60s to the 90s and 00s. For new farmers, intelligent equipment is more intimate and more popular than traditional tools. After the intelligentization of agricultural equipment, the demand for people, the benefits of intelligence is to reduce the dependence on experience, the requirements of production consistency Through intelligence.

 Finally, it is systematization. With the intelligent production equipment, the whole production process is interlocking. We will not see an isolated machine and equipment, but the organic combination of various production factors of the supporting man-machine method. The combination is good. A good solution, a bad combination, no matter how good the machine can not be effective, we must have a systematic thinking when discussing agricultural drones, or agricultural intelligent equipment applications, when discussing product design, must There is a concept of a solution.

 (3) What kind of agricultural drones or smart equipment is popular, can the product fall to the ground?

 We believe that there are six basic requirements:

 First, the effect is stable and reliable. This effect has a corresponding standard basis, and after rigorous scientific experiments and production practice verification, this process is also the most awkward in the agriculture-related industry, because we can quickly iterate through software, but agricultural production is one season to two seasons. I have to wait for the next year, and I will definitely have to do it without full verification;

 Second, the efficiency of contrasting labor is high. Only in this way can we cope with the large-area rapid deployment of the work, in order to have ten or even one hundred, in order to have promotional value;

 Third, there are supporting standard operating procedures. Intelligent equipment from the installation, commissioning, monitoring to the use of the process, maintenance and repair must have strict operating practices, in order to ensure less mistakes, to ensure efficient and continuous operation;

 The fourth is simple operation and durable leather. The use of smart devices minimizes manual intervention and dependence on experience. At the same time, it is used in agricultural production environments, with hot and cold weather changes, flying dust and liquid medicine, bumpy road bumps, and high-precision intelligence. Equipment is a severe test, and such high-standard products are also cost-sensitive, which is the most headache.

 Fifth, the corresponding technical support, pre-sales and after-sales service guarantees should form a system, including personnel training and spare parts supply. If you are busy with farming, you will not wait for someone. If you hit the drug halfway, tell the farmer that I want to pull back to the next level. I will come back in three days and I will definitely be beaten.

 Sixth, we must have economic benefits and form a healthy industrial chain. Whether it is a product or a model, it is necessary to be able to quickly and cost-effectively replicate and generate appropriate production efficiency to ensure economic efficiency. Ultimately, it depends on the return on investment.

 (4) Looking back at the past few years of experience, what problems have Green Guards encountered in practice?

 1. The verified data is seriously insufficient

 A very simple question, how wide is the spacing between the two nozzles of an agricultural drone? What is the appropriate static dynamic response? These problems require a lot of research and practice. After practice, we will in turn guide our product design. But the status quo is that these data are seriously inadequate.

 2, the land rules affect the efficiency of the operation

 The shape of our cultivated land in China is very strange. Even in the middle of the plot, there may be various kinds of sundries, such as electric poles and buildings. Such plots have a very large impact on the efficiency of farming.

 3, the medication program is uneven

 Pesticide spraying is the most important application of agricultural drones. Agricultural drones are used as spraying tools. The most important thing to achieve drug efficacy is medicine. Despite the gradual standardization of medication regimens, inconsistent medication regimes in different regions are still everywhere.

 4. The quality of personnel and the backwardness of agricultural infrastructure

 In the actual operation process, no matter the operators or customer personnel, the agricultural infrastructure is very backward in China, which is also an important manifestation of the immature status of our agriculture.

 5. Flight control and avionics systems are not for agriculture

 The core components include non-agricultural special use for flight control and avionics systems, and even the connectors and batteries used are not mature. The domestic agricultural drones are not very high-starting, most of them are transformed from the model aircraft. They are not used by agricultural drones. The lessons learned in this process are also painful.

 6. The supporting system of the plant protection machine itself needs to be improved.

 Agricultural drones are used for plant protection, and their own supporting guarantees are also urgently needed. For example, accessories, parts tracking, personnel training, spare parts purchase, although the two years have gradually matured, there are still many problems to be solved.

 (5) What other practical problems need to be considered in the process of agricultural drones in the field?

 First of all, it is the parcel analysis. If the land is neat and there are fewer obstacles around it, the flight planning of the flying hand will be easier.

 Secondly, the weather, the busy season of the farming industry is fleeting, and the agricultural drones need a certain preparation time, so it is necessary to consider the impact of the weather on the effects of the drone before the work.

 Third, the medication program. The drug regimen is the key to determining the effectiveness of plant protection. It involves issues such as how to dispense a drug, and how to use a drug-like dosage form.

 Fourth, process management. Agricultural production is a process of production operations, which requires standardized operation process management, such as how to plan the land, how to settle, garbage disposal, personnel dress protection and other issues are worth noting.

 (6) What kind of support is needed for agricultural drones to achieve universalization?

 We believe that there are five key elements in the following five areas:

 1. The government-led, sound and complete standards of laws and regulations can escort this emerging industry;

 Second, with the gradual opening of the application, the perfection of the industrial chain will accelerate the maturity of products and reduce manufacturing costs;

 Third, I hope that more and more professional manufacturers will intervene. From last year to this year, well-known manufacturers in the field of UAVs such as Dajiang, Feifei and Zero have all set foot in agricultural drones, which will improve the technical level of the entire industry. It must be a positive driving force;

 Fourth, any new industry, new products, essential consumer and user trial and error and the maturity of the educational process, no way, any product and market maturity must go through this hurdle, or faster or slower;

 Fifth, the innovation of business models outside the product, the business model innovation based on Internet + will certainly accelerate the integration of the above factors, and quickly ripen the industry.

 Recalling the representative harvester of agricultural mechanization, from introduction to popularization, forming a complete industrial chain, it took almost 10 years, but after the harvester formed a climate, the subsequent various farming and processing machinery quickly completed industrialization. the process of. We believe that as a representative of the intelligentization of agricultural machinery, agricultural drones will not be shorter than the popularization and promotion period of harvesters, but if the agricultural drones that are the masters of technology can take root, they will open the intelligentization of agricultural machinery as a representative. The door leads China's agricultural modernization to achieve leap-forward development. We also welcome everyone to join this industry or related industries to jointly promote the process of agricultural modernization in China! .

Application of UAV in Zhejiang Forestry

Zhejiang Province is a large province of forestry resources. Since ancient times, it has said that there are “seven mountains, one water and two fields”. The existing forestry resources are more than 99 million mu, and the forest coverage rate of the province is over 60%. The population of forestry areas accounts for the total population of the province. 63% of Zhejiang Province has a higher overall value of forestry economy and a stable forestry economic income. In recent years, Zhejiang Province has embarked on the path of innovative forestry economic development, emphasizing the first implementation of forestry modernization. As an important application method in the field of modern forestry technology, it has a wide application space and is of great significance for promoting the development of forestry economy. This paper combines the current situation and future needs of forestry economic development in Zhejiang Province, and explores the drone to Zhejiang Forestry in accordance with the ideas of scientific and technological innovation. Value.

 2.1 Forestry pest control

 UAV technology is mainly used in the prevention and control of pests and diseases in Zhejiang Province. It is specifically used to monitor and control large-scale pests and diseases. The monitoring methods based on drones effectively compensate for the shortage of manual monitoring. UAVs are used to obtain monitoring data and establish The insect light with automatic data transmission function can effectively carry out the monitoring of pests and diseases, thus forming a scientific and comprehensive biological prevention and control monitoring system. The monitoring system based on drones can establish a wide-ranging pest and disease monitoring mechanism, which can comprehensively monitor the pests and diseases of common forests such as pine, bamboo, economic forest and cedar in the province, and can meet the monitoring of difficult areas in Zhejiang. Need to be able to use large unmanned aerial vehicles to clean up pests and diseases in the event of a sudden outbreak, which is to improve the response speed of responding to pests and diseases, better transmit the spraying of pesticides through airborne equipment, reasonably control the density of spraying pesticides, and pesticides. It is of great significance to assess the use, reduce the cost of pesticide spraying, improve the quality of pest control work, and meet the needs of Zhejiang's forestry economic development.

 2.2 for forest fire prevention

 Forest fire prevention is the top priority of forestry management. The key elements of forestry fire prevention work are to detect fires in advance and improve the observation of complex forestry areas. Professional control patrols for high-risk areas prone to fire. The risk of forest fire prevention is high, and it is necessary to accurately grasp and control the fire source. The UAV based on satellite remote sensing technology can meet the aerial imagery required for high-precision forestry fire prevention, help to reduce the problem of poor ground measurement accuracy, and also obtain high-resolution, high-precision, high-utility image resources. Contemporary new drones can already take off and land in complex areas. UAVs can load corresponding equipment to control the ground area, and can be close to observation, which is of great significance for accurately grasping the fire. At present, most of the UAVs deployed by the forestry departments of Zhejiang Province have high-definition digital lenses and multi-spectral imaging equipment, which meet the requirements of patrol navigation according to the established route, and can also obtain data information in real time. And there have been drones to improve the monitoring of fires during the high-incidence period. Through drones, timely detection of fires, timely reporting of fire information, control of losses, reduction of fire costs, and effective reduction of energy consumption for disaster relief have been achieved. Meet the fire rescue needs. At the same time, the forestry department pays attention to the implementation of fire-fighting responsibilities through drones, emphasizes the strengthening of the control of wild fire sources, and strives to form a drone operation team operated by special personnel to meet the application needs in complex environments.

 2.3 Wildlife Monitoring

 At present, drone technology is also used for wildlife monitoring, emphasizing the improvement of timeliness and efficiency of monitoring through wildlife monitoring. The drone's monitoring of forest wildlife has functions unmatched by other equipment, because the drone has a more flexible viewing angle, features convenient photographing and full angle, and the drone does not carry flammable and explosive substances, electric drones. The longer life time, the long-term monitoring of the wild fauna can be achieved, so as to achieve the goal of mastering the distribution of wild animals in Zhejiang Province.

 2.4 Forestry Resources Planning and Research

 Zhejiang Province has clearly defined the goal of deepening the comprehensive reform of forestry, emphasizing moderate development of scale operations, striving to develop precious colored forests, implementing the plan for new planting precious trees, and clarifying the task of maintaining national ecological security. The achievement of these tasks is largely based on effective forestry planning surveys. In order to better formulate forestry development plans and effectively establish forestry information systems, it is necessary to obtain high-precision image information based on satellite images to ensure that the images are intuitive, clear and clear. The use of drones for image capture can effectively compensate for the insufficiency of satellite imagery, which can eliminate the influence of factors such as climate change and complex terrain in Zhejiang mountains, thus effectively compensating for the poor resolution of satellite image shadows and homomorphisms. The problem. Low-altitude observation drones can obtain rich high-resolution images, achieve the goal of quickly obtaining surface information, help to present the reality of three-dimensional surface morphology maps, and achieve effective access to forestry data information goals.

 2.5 for forestry planting

 The UAV remote sensing image technology can carefully and comprehensively classify the forestry resources in Zhejiang Province, and help to obtain first-hand detailed data of forestry planting area, growth, rotation, etc. Methods, forestry fertilization, simultaneous monitoring of forestry planting area, and a reasonable division of forestry industry structure have important guiding value. The development of forestry based on drones can achieve the goal of high efficiency and low cost, and is of great value for promoting the large-scale production of Zhejiang forestry economy. At present, large, medium and small drones have been widely used in forestry production practices, and different types of drones are responsible for different production tasks.

 3.1 main advantages

 UAV has a wide application space in the forestry field and can undertake a variety of specific application tasks. 3S technology, remote sensing technology, digital image technology and real-time transmission technology based on UAV platform can meet the practical needs of forestry production and scientific research. It can help improve the speed, effectiveness and innovation of forestry management, and improve the speed and quality of forestry problem processing based on faster grasp of first-hand data information. Especially in the current development of various load drones, the restrictions are getting smaller and smaller, which can meet the operational needs of complex mountainous conditions in Zhejiang Province, help to reduce the fatigue of human resources, and play The value of hazardous forestry missions. Based on various mission requirements, the UAV can be flexibly configured to form a diversified UAV application system that performs tasks, thereby achieving the goal of utilizing the advantages of the UAV. It can also obtain a large amount of accurate data information, and can transmit data based on 4G terminals, thereby improving the real-time performance of data transmission and meeting the specific needs of the application.

 3.2 main issues

 Zhejiang Province is a mountainous province. The coverage of forest resources is wide, the terrain is complex and changeable, and the terrain is fluctuating. Therefore, it affects the detailed indicators of data transmission by drones to a certain extent. Especially in the current situation of increasing the details of forestry data information, there is a certain risk that the drone will perform the aerial survey task. China still lacks professional operation of drone technicians. The existing personnel use the technology of drones without mastering complex terrain, which reduces the performance of drones in actual work. Although the ability of UAVs to adapt to the environment is strong, it is necessary to develop large, medium and small types of UAVs. At present, there are many small UAVs in the grassroots forestry departments, and there are fewer medium and large UAVs. There are fewer unmanned helicopters, and the existing drones sometimes do not meet the actual needs of Zhejiang forestry. Moreover, there is still a problem that the cost of applying the drone is high, and the operation and maintenance of the drone are not timely, which greatly affects the service life of the drone and hinders the expansion of the application field of the drone.

 4.1 Development of quality drones

 The UAVs currently used in the forestry field in Zhejiang Province are mainly small UAVs, and the application of large UAVs is relatively small. The cost of applying UAVs to forest fire fighting and spraying pesticides is relatively high. In order to better meet the application needs in the forestry field, it is also necessary to establish a research and development team for drones based on forestry work. The forestry department and the drone companies will cooperate to effectively develop the requirements for forestry, which can be used for surveying, meteorology and remote sensing. Large and medium-sized drone equipment with mechanical operations. Especially with the development of complex forestry projects, the current UAV industry needs to carry equipment, so as to contribute to the needs of mountain forestry construction and meet the needs of Zhejiang's forestry economic development.

 4.2 Establish a data resource library

 At present, drones have been widely used in vegetation pollution monitoring, pest and disease monitoring, and a wide range of forestry data and information resources can be collected based on drones. Establishing a typical plant data resource base based on drones is of great value to the development of forestry environment. Therefore, it is necessary to further develop the application value of the UAV from the current situation of Zhejiang's forestry development and construction, pay attention to the water quality monitoring work in the forestry area through drones, collect data information such as non-point source pollution and bird migration, and build high quality. The database system achieves the goal of continuously enriching forestry data resources based on drones. With the increasing use of drones and the continuous improvement of real-time transmission systems, it is necessary to develop a professional UAV database system to effectively summarize the forestry information collected by UAVs.

 4.3 Improve the applicability of the application

 UAVs have important value for forestry construction. In order to better play the practical role of drones, we must strengthen the management of the use of drones, effectively improve the scientific and norm of UAV applications, and ensure the use of drones. Practical features. First of all, strengthen the exchange of UAV application technology, better promote the UAV technology, and meet the actual needs of the grassroots UAV application. Secondly, strengthen the training of UAV application technicians, promote the UAV application technicians to master advanced UAV application methods, and effectively exert the practical application value of UAVs. For example, in October 2018, Longquan Forestry Bureau invited Wenzhou Huifei Company to conduct more than 60 trainings for drone aerial photography training, and purchased more than 30 drones. Greatly reduce the work intensity of field workers in the field. Third, it is necessary to reduce the application cost of drones, focus on improving the rationality and standardization of drone maintenance work, increase the application management of drones, and effectively prevent the occurrence of UAV application accidents.

 UAVs have broad application value in Zhejiang forestry production, planning, research, and reduction of forestry risks. Although UAVs are subject to subjective and objective conditions in the forestry field, they should see the practical application value of drones. Focus on the development of multi-type forestry UAVs, combine UAVs with specific tasks, and effectively realize the value of UAVs in innovative applications.
