| The science and technology are developing rapidlly. With the pace of our entering the information age, the intelligent video technology is booming. The development of hardware technology promotes the video resolution expanding to some extent, on the other hand, the video data, captured by capture devices, are mounting rapidly. Software technology continues to be more mature, which leads to the complexity of video processing algorithms. With the continuous development and improvement of software and hardware, technology of video surveillance is developing toward the intelligent direction.The result of development of science and technology should be widely used into our daily life, however, ordinary people have not benefit from it. There is a serious disconnect between the development and application of intelligent video technology. Fortunately, the intelligent video technology in our life will be more and more used with an irreversible trend.We studied and implemented the "Video Surveillance System" based on TI DaVinci processor,which aims to design a video analysis system used for security work. The system have four analog capture devices, combined with intelligent video analysis algorithms, making the presence of risk factors can be easily detected. The owner can view the situation around the body through a network in real time, which may prevent threaten of personal safety and property security.The "Video Surveillance System" is based on DM8127 processor core, which builds a surveillance system,combined of acquisition, processing, testing and analysis technology. In detail, we finished debugging work on two kinds of video capture device, CMOS image sensor camera and analog monitor. After the capture of video data, we should construct the video data link to achieve our goal of design. After designing of cumulative timing algorithm and feature points grouping algorithm for the system, we can get adapted intelligent video analysis system applied to a specific scene. |
