A high-definition video intelligent processor for abnormal event alarm

Abstract

The invention provides an abnormal event alarm high-resolution video intelligent processor. An A / D (Analog to Digital) processing unit in the high-resolution video intelligent processor is accessed to perform digital processing on a high-resolution video, and outputting video streams to an intelligent video analysis unit DSP (Digital Signal Processor); and the intelligent video analysis unit DSP is used for outputting the video stream superimposed with analysis data to a H.246 video encoding unit for compressed encoding, and outputting target detection and feature extraction data to a central processing unit ARM (Advanced RISC Machine) for performing abnormal event management and judgment. Distributed hybrid architecture is adopted, and abnormal event modeling is performing on the basis of a business rule, so that the functions of acquisition, encoding, intelligent analysis, alarming, compression, network transmission and the like are realized on high-resolution video streams of 1080P and more than 1080P, and an integral solution is provided for intelligent analysis and processing of high-resolution video images.

Description

technical field [0001] The invention is applicable to the fields of public safety and anti-terrorism and anti-riot, and in particular relates to an intelligent high-definition video processor for alarming abnormal events. The present invention can perform functions such as collection, encoding, intelligent analysis, alarm, compression, and networked transmission of 1080P and above high-definition video streams. Background technique [0002] With the enhancement of high-speed digital signal processing (DSP) performance, the video intelligent analysis algorithm can be transferred from CPU processing to DSP real-time processing, and the intelligent video analysis platform is gradually developing from pure software video analysis to embedded direction. Embedded video analysis can be used in The front end directly processes the video information, which has high real-time performance. Currently, using DSP and image processing algorithms to implement embedded video analysis is the...
