Abstract

The application provides a people counting method and device. The method comprises: performing target segmentation on a current frame image detection area to extract a moving foreground object; detecting the head and shoulder characteristic frame in the moving foreground object; determining whether the head and shoulder characteristic frame in the moving foreground object meets people counting trigger conditions; and counting people according to the head and shoulder characteristic frame when the head and shoulder characteristic frame meets people counting trigger conditions. The people counting method and device can shorten characteristic detection time, reduce a characteristic false drop rate, improve characteristic detection effects, and thereby increase people counting efficiency and accuracy.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a method and device for counting people. Background technique [0002] Real-time people counting systems are deployed in many public places (such as shopping malls, supermarkets, parks, etc.), so that managers can grasp the real-time passenger flow situation, take necessary diversion measures, and prevent dangerous events such as stampede due to too many people. [0003] The current people counting method is mainly based on video detection. Cameras are installed at the entrances and exits of public places to collect video, and then the collected images are analyzed to finally count the number of people in the place. For example, the method of background modeling plus feature library matching is used for pedestrian detection, or multiple head classifiers are used for head detection. However, the above-mentioned people counting methods generally have problem...
