The position of intelligent video surveillance in the security market can not be underestimated. In order to meet higher and higher security requirements, a new type of intelligent video surveillance technology is proposed. It consists of video capture, intelligent video analysis and monitoring, and the physical architecture includes central and decentralized. The traditional video surveillance system includes the first generation of analog surveillance systems, the second generation of digital local video surveillance systems, and the third generation of digital remote video surveillance systems. In order to solve these problems, relevant technologies in computer vision are introduced into video surveillance to develop new video surveillance technology—intelligent video surveillance. The technology is based on digitized and networked video surveillance. With the help of a computer's powerful data processing capabilities, it can automatically analyze and extract key information from video sources, which can be supervised by computers.
In the current decentralized analysis work will be given to the encoder or IP camera to analyze the movement of the target's behavior, the decision-making alarm module according to the video image processing results and predetermined alarm rules, complete the start of the alarm judgments and decisions, in the alarm At the same time realize the video of the sports goal. The analysis is done by the DSP of the front-end device. Mainly include: Based on DSP + FPGA dual processor implementation, based on dual DSP implementation, based on single-chip DSP implementation. In addition to the advantages of a general digital surveillance system, intelligent video surveillance also has the characteristics of 24/7h reliable weather monitoring, high alarm accuracy, fast response, and effective use of video resources. Therefore, with the popularization of video surveillance and the improvement of monitoring requirements, the scope of application of intelligent video surveillance will continue to expand. The intelligent video analysis module receives the alarm rule settings sent by the upper computer; performs high-speed analysis and data processing on the image content captured by the fixed camera, achieves target detection and recognition, and compares pre-set alarm rules or conditions set by the user to give an early warning and alarm Or handle the result. In combination with the traditional analog video surveillance system, the intelligent video surveillance system has more powerful image processing capabilities and intelligence factors than an ordinary network video surveillance system on the basis of effective information acquisition.
