One, application background
Traditional monitoring will produce the mass of the original video, if the original video using artificial classification, sort and abnormal event detection, the workload is very large. This task is very time-consuming, because it is a must watch the video to determine whether record abnormal events. Although the tedious task in your personal video collection may be feasible, but when it is monitoring camera and network camera recorded endless original video, it is almost impossible to finish. For example, only in Beijing, there are millions of surveillance camera, covers the city streets, each camera recording 24 hours/day. Because video huge, so most of the surveillance video has never been seen or inspection. This paper aims to use computer video analysis and processing of digital video data, get the "typical" content, in brief, the user can read the outline of the representation, the lowest possible price (network transmission bandwidth, time, storage) for the user to browse or inquires the preview video database.
Two, the function overview
From the original video extract moving target, the moving target enter or leave the pictures, the trajectory happen greatly change save monitoring screen picture.
According to the time, location, objects such as size information of moving target retrieval. Moving target images with snapshot list of way to show. Can quickly positioning target video clips to play.
Three, the technical implementation
At present video the system through the hard disk video recorder access quasi real-time video, the results will be stored in the database.
The user through the customer terminal retrieval and view the results.
Four, the application and the customer benefit
(a) greatly reduce later video back to check the cost of labor.
(2) according to the target time, position, size of object condition such as rapid positioning interested target.
(3) through the small storage cost long time preservation monitoring results.
Five, involving the product
Video the host.
