Abstract

The invention provides a people counting method based on elliptical ring template matching. The method comprises the following steps of: (S1) getting a video stream image in a monitoring area as an input image; (S2) performing edge detection on the input image through a Sobel operator to get an edge image; (S3) getting a differential image by processing through a background subtraction method according to the input image, and further performing binarization processing on the differential image to get a moving object area; (S4) combining the edge image with the moving object area, performing and operation, and extracting common parts to get moving object contours; (S5) scanning the moving object contours through a plurality of elliptical ring templates, and performing contact ratio Co calculation to extract pedestrian contours and the mass center of each pedestrian contour; and (S6) tracking and counting the mass centers based on a nearest neighbor matching and tracking method of a Kalman wave filter to get the number of people. The people counting efficiency and the accuracy are improved by matching the plurality of the elliptical ring templates with the moving object contours.

Description

technical field [0001] The invention belongs to the technical field of video image processing and recognition, in particular to a people counting method based on ellipse ring template matching. Background technique [0002] In the management and decision-making of shopping malls, shopping centers, airports, stations and other public places, the flow of people is an indispensable data. Through the statistics of the flow of people, that is, the number of people entering and leaving, it is possible to effectively monitor and organize the operation of public places in real time, and provide people with a safer environment and better services. Taking shopping malls as an example, the flow of people is a very basic and important indicator, which is closely related to the sales volume of the mall. If you know the more accurate and real flow of people, you can provide reliable reference information for sales, service and logistics. [0003] The traditional people counting m...
