A kind of Multi-target position tracking video frequency monitoring method

A kind of Multi-target position tracking video frequency monitoring method, is fixed, there are the moving target locating and tracking video frequency monitoring methods of the small dynamic change of object for background suitable for camera field of view.Background is trained by gauss hybrid models first before system work, then obtains foreground image with background subtraction method in video next frame, accurate foreground object region i.e. moving target position is obtained further according to dilation operation and medium filtering；Detection moving target whether there is, and determines target location according to connection domain lookup if moving target exists, video next frame is proceeded to if no moving target；Tone space conversion is carried out to target location area image and weights NTSC space hue figure I and HSV space tone illustration H to obtain hue histogram, the back projection of image is further obtained, is then accurately positioned target location with Meanshift algorithms.It is calculated more than into the next frame repetition of video.The present invention can be used as movement objective orbit analysis, overspeed of vehicle and in violation of rules and regulations detection and Pedestrian flow detection.
