Abstract

The invention provides a multi-region people counting method based on a single camera, and the method comprises the steps: S1, collecting an image through the camera, and carrying out the preprocessing of the image; S2, respectively sending the preprocessed images to a detection network and a regression network; and S3, carrying out region division on the camera picture, and carrying out region judgment on the position of each target. When the method is applied to a real application scene, a detection result and a regression result are verified and judged, the real-time number of people in multiple areas in a single picture can be accurately and reasonably output in real time. The number of people in the whole picture is monitored, and meanwhile, a plurality of different specific areas aresupported to be specified, so that the time cost and the labor cost of statistics and monitoring are saved, the trouble caused by frequent statistics of the number of people in real time is avoided,and the unnecessary loss and the possibility of accidents are reduced.

Description

technical field [0001] The invention belongs to the field of video surveillance, and in particular relates to a method for counting people in multiple regions based on a single camera. Background technique [0002] With the development and progress of society, more and more scenes will have crowds gathering. However, the high-density scenes that appear when crowds gather bring many safety hazards. For example: gatherings in squares, the Bund, and festival celebrations are prone to safety hazards such as stampedes. Therefore, it is particularly important to monitor the crowding degree of the crowd in a timely manner, reflect the changing trend of the crowd number in different areas, and provide timely manual intervention. In addition, there is also a need for people counting in scenes such as queuing and restaurant dining. The existing regional people counting scheme cannot know the specific number of people in a certain area under a single camera, but can only reflect the ...
