DM8168 intelligent video surveillance system function introduction

1, regional intrusion detection

In view of the enterprise's important areas such as financial room, record room, warehouseand other sensitive areas, on the video screen, setting the forbidden area, regionalintrusion detection enabled system, if people cross the picket line or in the occurrence ofabnormal circumstances prohibited area preset, intelligent analysis system will lock boxlocation specific calibration target recognition in the picture, began to object tracking,remind the company leadership attention, timely stop.

2, behavioral analysis

Now in the office network era, corporate secrets will be leaked, be an easy job to have an ulterior motive employees at the same time, how to regulate the behavior of office staff,improve staff work time and work efficiency. Monitor screen in the workplace, enable intelligent behavior analysis and detection function, to detect abnormal behavior for the deployment period in the region, to meet the system default behavior when the trigger system, prompt and alarm, the discovery of abnormal, nip in the bud, the company's loss of control in the smallest scope.

Article 3, retention, mobile detection alarm

In the enterprise after work, various objects office in the unattended state, this time if abnormal situation occurs, may be on the enterprise property irreparable damage.Regional settings in the video picture of surveillance cameras, mobile, enabling goodsstranded detection alarm function. When setting the region objects disappear or be moved,automatic alarm system, at the same time, the system will according to the preset function,a SMS will send field situation to set a good mobile phone, notify the relevant personnel,remind the abnormal situation.

4, fireworks, smoke detection alarm storm

In the visual scene range surveillance camera, the DM8168  system can arbitrarily set the alert area,when a flame or smoke appeared and reached the field value upper limit, triggering prompt or alarm. Complete intelligent video analysis based on the detection of flame, the role of distance, the detection results are not affected by the temperature of the environment, tosmoke detection in key areas, can prompt or alarm to avoid the situation to expand in the first time.

5, message linkage function

DM8168 alarm linkage classification as intelligent monitoring system features. It will alarmevents in the first time will text message or site pictures MMS issued to the system settings of the person in charge on the mobile phone. If the next level is responsible for the relevantpersonnel not treatment on the alarm, then in the set time, the equipment will automaticallytext messages sent to a higher level of leadership, not limited size, this can through the multilayer management penetration to field personnel timely processing, will be time to minimize the loss of close degree, do things can and, prevent trouble before it happens.The MMS also shows the suspect via path, time, location, behavior and other information.

6, the lens unusually intelligent alarm

Under normal circumstances the, by climate (Yin, sunny, rain, snow white,) and dayalternate natural changes, strong adaptive ability of environment with DM8148 system,through the video capture device optimization and system through self adapt backgroundlearning process day scene change, able to video for all-weather uninterrupted intelligent analysis.

Video image caused by the non natural factors also have abnormal, system self protectpowerful. Encountered because people or extremely bad weather caused fatal damage to the video equipment or circuits, such as video jitter severe, no video signal abnormal condition, the system will start from the protection warning mechanism, the prompt centermanagement personnel for maintenance treatment of surveillance camera.

DM8168 Function Available for CCS

I implemented LU decomposition algorithm to find the inverse of a 36 x 36 complex matrix (In turn I had to convert this in to a 72 x 72 matrix before I could pass it to the matrix inverse algorithm). This is increasing the CPU cycles required for the computation and hence my C - code is not meeting the time requirement.

I was wondering if there is any DSP especially DM8168 library function available to find the inverse of a complex matrix? I checked the forum but couldn't get much help.

If there is no such library function available for CCS, I would appreciate if somebody can guide me towards better complex matrix inverse algorithms or ideas.

Refer to Single precision DSPF_sp_lud_inv_cmplx and Double precision DSPF_dp_lud_inv_cmplx functions in the DSP library version 3.4.0.0.

Is there a DSP like DM8168 Library programmer's reference guide document available for this 3.4.0.0 version?

The documents included in the DSP library installer with user manual in doxygen form.

DM8168 Development Board Overview

2011 March 2  in Beijing / PRNewswire Asia / - a few days ago, TI (TI) announced the launch of a high performance TMS320 DM8168 Da Vinci (DaVinci) digital media processor and the software is compatible with the low power Da Vinci TMS320 DM8148 digital media processor, further expanding the Qi Dafen Qi digital media processor platform product camp.

Using these two industry leading video processor, TI will help realize video communication lifelike, brings communication more excellent experience for the people, strengthen the public security, the real-time vehicle vision system for safer driving, and brings the highest quality for consumer entertainment experience, all in all,

This is not the only one. Compared to high performance DM8168 Da Vinci digital media processor and competing solutions, can provide 3 times the video stream processing function, combination synchronization video supports up to 3 1080p at 60 frames per second flow, 12 720p30 FPS synchronous video stream or multiple lower resolution video streams.

This can help customers build a system based on video as the center, at the same time in as many as 3 independent screen capture, coding, decoding and analysis of multiple video streams.

In addition, it can also through advanced analysis features to help customers achieve product differentiation.

This product is ideal for Multi Channel HD video monitoring system, video conference system, media hub and the server and video broadcast system.
