Abstract

The embodiment of the invention discloses a crowd density statistics method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining a to-be-counted target image comprising crowd information; inputting the target image into a pre-trained target detection deep neural network to obtain a first crowd density distribution diagram corresponding to the target image; inputting the target image into a pre-trained crowd density regression deep neural network to obtain a second crowd density distribution map corresponding to the target image; and fusing the first crowd density distribution diagram and the second crowd density distribution diagram through a pre-trained fusion neural network to obtain a third crowd density distribution diagram. The problem that crowd density distribution in different crowd degree scenes cannot be well processed during crowd density statistics is solved, and the universality and accuracy of crowd density statistics application are improved.

Description

technical field [0001] The embodiments of the present application relate to computer vision technology, and in particular to a crowd density counting method, device, electronic equipment, and storage medium. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, people's social activities are gradually increasing, and the congestion of traffic hubs, large-scale event sites and large public places is becoming more and more serious, and the safety hazards caused by crowd congestion are becoming more and more serious. Therefore, how to automatically and real-time count people has important research value. [0003] In actual situations, the crowds in different scenes have obvious differences, and the crowds in different time periods in the same scene have huge changes. For example, in a subway station, the crowds during the peak commuting period and the flat peak period vary greatly. In addition, due to th...
