Embodiment Construction

[0020] The present invention provides a method and device for counting people based on video in order to count people in outdoor environments and improve the accuracy of people counting.

[0021] The embodiments of the present invention will be described in detail below with reference to the drawings in the specification.

[0022] figure 1 It is a schematic diagram of a video-based people counting process provided by an embodiment of the present invention. The process includes the following steps:

[0023] S101: Obtain video information for detecting an area to be detected, and identify the motion foreground of each video frame in the video information.

[0024] In the embodiment of the present invention, a camera may be set in the area to be detected to monitor the area to be detected, and the video information of the area to be detected can be obtained through the camera.

[0025] In the embodiment of the present invention, the background of the video information remains unchanged for...

Abstract

The invention discloses a method and a device for carrying out statistics on the number of people on the basis of a video and solves the problem that currently, when the number of people is subjected to statistics, the number of people cannot be accurately subjected to statistics caused by that bonding between people and a person video image cannot be identified. The method comprises the following steps of: identifying a moving foreground which monitors video information and carrying out binarization processing on each video frame, so that after binarization processing, the moving foreground in each video frame is formed by white pixels and a background in each video frame is formed by black pixels; aiming at each white pixel and according to pixel values of other pixels adjacent to the white pixel, determining white pixels positioned on bones of human bodies and pixels positioned in regions where heads of people are positioned; and according to the determined pixels positioned in the regions where the heads of people are positioned, carrying out tracking statistics on the number of people. According to the embodiment of the invention, the white pixels on the bones of the human bodies are determined, so that thinning processing on the human bodies is implemented and the problem of bonding between people can be effectively solved, so that accuracy of statistics on the number of people is improved.

Description

Technical field [0001] The present invention relates to the technical field of video image processing, in particular to a method and device for counting people based on video. Background technique [0002] With the continuous development of social economy, more and more public places such as entertainment and leisure have appeared. These public places can be supermarkets, chain stores, department stores, large shopping malls, hotels, KTV, etc. How to count and analyze the number of people in key monitoring areas of public places such as entertainment and leisure has become a relatively important technical problem. [0003] At present, the number of people can be counted through methods such as smart people counting. Smart people counting is the analysis of video images, image processing, pattern recognition and other processing, and the statistics of the number of people in a designated area. However, this statistical method is mainly aimed at indoor or short-distance scenes. For ...
