Problems solved by technology

[0003] In recent years, with the rapid development of computers and other related fields, such as the development of image representation and multimedia processing technology, video processing has changed from a specialized research field to a common one in scientific research and human-computer interface. However, because video equipment or monitoring equipment needs to identify and track targets in communication engineering, some current video data processing systems only perform data analysis and transmission on analog video data when processing video data. And the cost is high, and it is impossible to guarantee the normal processing and display of the information collected by the video equipment
