Pedestrian flow funnel generation method and device, storage medium and electronic equipment

Abstract

The invention relates to the technical field of data processing, in particular to a pedestrian flow funnel generation method and device, a storage medium and electronic equipment. The method comprisesthe following steps: acquiring a current frame image, and tracking and updating a head and shoulder region in a tracking sequence set in the current frame image according to a multi-target tracking algorithm; obtaining a head and shoulder region in the current frame image according to a head and shoulder recognition model, and updating the tracking sequence set according to the head and shoulderregion in the current frame image; and analyzing the motion track of each head and shoulder region in the tracking sequence set to count the pedestrian, and when the current frame image is the last frame of image, generating a pedestrian flow funnel based on the counting result of the pedestrian. According to the pedestrian flow funnel, the head and shoulder regiondetection accuracy is improved, missing detection of the head and shoulder region is avoided, the pedestrian counting accuracy is further improved, and therefore the pedestrian flow funnel accuracy is improved.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular to a method and device for generating a pedestrian flow funnel, a storage medium, and an electronic device. Background technique [0002] With the continuous progress of society, the application range of video surveillance system is getting wider and wider. Surveillance cameras are often installed at the entrances and exits of places such as supermarkets, shopping malls, gymnasiums, and airport stations, so that security personnel and managers can monitor the entrances and exits of these places. On the other hand, the flow of people entering and leaving places such as supermarkets, shopping malls, gymnasiums, and airport stations is of great significance to the operators or managers of the above places. Among them, the flow of people refers to the number of people flowing in a certain direction. Refers to the number of people flowing in both directions by enter...

Problems solved by technology

This method of manually counting the flow of people is relatively reliable when the monitoring time is short and the flow of people is sparse, but due to the limitation of the biological characteristics of the human eye, when the monitoring time is long and the flow of people is dense, the statistical accuracy will be greatly reduced ( That is, there will be missed detection), and the way of manual statistics needs to consume a lot of labor costs

On this basis, if you want to count the gender and age of the flow of people, the efficiency and accuracy of the statistics will be further reduced, and the cost will be increased.

In addition, due to the low statistical accuracy of people flow and gender and age, the accuracy of the traffic funnel obtained based on the inaccurate statistical data of people flow and gender and age is not high, so that the statisticians cannot obtain the results through this traffic funnel.
