The invention provides a method and a device for detecting static targets. The method comprises the following steps of: step one, dividing a monitoring area into a plurality of monitoring area blocks and obtaining image blocks corresponding to each monitoring area block in each frame video image; step two, calculating the characteristic values of the image blocks; step three, carrying out statistics in real time to the characteristic values of the image blocks corresponding to each monitoring area block to obtain statistical result corresponding to each monitoring area block; and step four, according to the statistical result, carrying out initialization to the background images of the monitoring area blocks, detecting static targets in the video images or carrying out updating to the background images. The invention can carry out real-time analysis to monitoring scenes based on the statistics, is not easily interfered by noise, can process the condition that the static target is blocked, and solves the technical problems that the prior art is easy to be interfered by noise and can not process the condition that the static target is blocked.
Description
technical field [0001] The invention relates to the field of intelligent video monitoring, in particular to a method and device for detecting stationary objects. Background technique [0002] Video surveillance technology emerged with the development of video collection and transmission technology. Traditional video surveillance uses manual methods to observe whether there are suspicious events in the surveillance video, without adding any intelligent processing functions. Its disadvantage is that it is impossible for monitoring personnel to maintain a high degree of vigilance for a long time, so it is impossible to maintain the accuracy of monitoring at all times. Intelligent video surveillance applies intelligent processing technology to video surveillance, which can automatically and intelligently process and analyze surveillance video data around the clock to determine whether any suspicious events have occurred. With the gradual popularization and deepening of security...
