People counting method and device based on head shoulder detection

Abstract

The invention discloses a people counting method and device based on head shoulder detection. The people counting method based on head shoulder detection comprises steps of S1 arranging a heat area and a base line in a monitor video, S2,performing head-shoulder detection on the heat area in the image frame of the monitor video, S3,determining whether the head and the shoulder exist according to the head shoulder detection result, if yes, executing the step S4, S4 setting a head-shoulder frame and maintaining or updating a tracking list and continuing to execute the step 6, S6, performing tracking on each head-shoulder frame in the tracking list to obtain a group of tracking frames, S7, determining whether the tracked head-shoulder frame in the current frame satisfies a people counting trigger condition, S8, starting up a counter and performing people counting according to the tracked head-shoulder frame. The invention discloses a people counting device based on the head-shoulder detection. The people counting method based on the head-shoulder detection is wide in application range, high in detection, low in false detection rate and high in tracking performance.

Description

Technical field [0001] The present invention relates to the field of computer vision and image processing, in particular to a method and equipment for counting people based on head and shoulders detection. Background technique [0002] The people counting system can count the number of people passing through the monitoring area within a period of time, realize multi-directional people counting, and provide information such as crowd movement. According to different application needs, users can specify to monitor one or more entrances and exits, and can also specify a single direction or two-way crowd flow statistics. The people counting system can be widely used in public transportation vehicles, long-distance vehicles and large shopping malls, shopping malls, exhibition halls, customs, museums and exhibition halls and other places, and provides indispensable data for the management and decision-making of these public places. For the retail industry, the flow of people is a very ...

Problems solved by technology

[0007] In order to solve the technical problems of low accuracy and unusable complex background in the people counting system in the prior art, the present invention proposes a method for counting people based on head and shoulder detection, which includes the following steps: Step S1: In the monitoring video, a hot zone for head and shoulder detection and a baseline for people counting are set; step S2: perform head and shoulder detection on the hot zone in the image frame of the monitoring video; step S3: detect according to the head and shoulder As a result, it is judged whether there is a head and shoulders; if there is, then step S4 is performed; step S4: set the head and shoulders frame and maintain or update the tracking list, the tracking list is used to store the head and shoulders frame that needs to be tracked, and continue to perform step S6; step S6: Track each head and shoulders frame in the tracking list to obtain a group of tracking frames; Step S7: Determine whether the tracked head and shoulders frame in the current frame meets the people counting trigger condition; if it meets the people counting trigger condition, Then execute step S8; if the people counting trigger condition is not satisfied, return to step S2 to detect the next frame; step S8: start the counter, and perform people counting according to the tracked head and shoulders frame
