Abstract

The present application discloses a crowd density determination method, device, equipment and storage medium. Including: acquiring the image of the crowd to be detected, which is an image obtained by an image acquisition device obliquely above the crowd; performing head detection on the portraits in the image of the crowd to be detected to obtain key points of the head; key points of each detected head Points are density clustered to obtain multiple crowd areas in the crowd image to be detected, and the difference between the average head area of ​​each crowd area in multiple crowd areas is greater than the preset threshold; calculate the number of crowd areas in each crowd area Crowd density; based on the crowd density of each crowd area, determine the crowd density corresponding to the crowd image to be detected. By adopting the method for determining the crowd density provided in this application, the influence of the occluded body of the portrait in the image on the calculation result of the crowd density can be reduced.

Description

technical field [0001] The present application relates to the technical field of crowd density estimation, in particular to a crowd density determination method, device, equipment and storage medium. Background technique [0002] Crowd density estimation refers to the estimation of the density of dense crowds, which can generally be used in security scenarios such as shopping malls, hospitals, squares, stations, etc., to prevent confusion, stampede, blockage of fire exits, etc., or to predict queue length Or wait a long time for traffic scheduling. [0003] In practical applications, crowd density estimation is generally performed by analyzing and processing crowd images collected by cameras. However, there are various problems in the actually collected crowd images, for example, mutual occlusion, incomplete portraits, close portraits, far small portraits, etc. The traditional crowd density estimation method has poor effect and poor accuracy in crowd density estimation for...
