Visitor flow rate statistical method and device based on image recognition

Abstract

The embodiment of the invention discloses a visitor flow rate statistical method and device based on image recognition, and the method comprises the steps: sequentially obtaining target human faces in N target images, so as to obtain a first target human face set, wherein N is a positive integer; carrying out the filtering of the first target human face set based on a human face tracking algorithm, so as to obtain a second target human face set; carrying out the filtering of the second target human face set based on a human face feature value real-time clustering algorithm, so as to obtain a third target human face set; and counting the target human faces in the third target human face set, so as to obtain a visitor flow rate statistical value. The method carries out the two-layer filtering of N target images, and can accurately filter out repeated human faces in the target human faces, so as to avoid the repeated counting of target human faces, and improve the visitor flow rate statistical accuracy.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a method and device for counting people flow based on image recognition. Background technique [0002] In many scenarios, the flow of people entering a certain checkpoint or area is very useful information. This requirement widely exists in many environments such as security, transportation, and commerce. issues of continuing concern. [0003] At present, the statistics of people flow can be divided into physical solutions based on access control or turnstiles and solutions based on video image analysis. However, based on the poor passability of physical solutions such as access control or turnstiles, the existence of access control turnstiles greatly limits the speed of the flow of people; and the overall cost is high; and the existing method of counting the flow of people based on video image analysis uses The main idea of ​​is to count the number of target faces appear...

However, based on the poor passability of physical solutions such as access control or turnstiles, the existence of access control turnstiles greatly limits the speed of the flow of people; and the overall cost is high; and the existing method of counting the flow of people based on video image analysis uses The main idea is to count the number of target faces that appear in the video frame image, but obviously the target face may appear repeatedly in different video frames, so that the count is not ready
