A method and system for passenger flow statistics based on binocular vision

Abstract

The invention belongs to the field of passenger flow statistics, and discloses a method and system for passenger flow statistics based on binocular vision. The method includes obtaining a first image and a second image, and establishing a Target solid model; obtain the target height of each target according to the highest point of each target in the target solid model, and select target components from multiple targets in the target solid model according to the target height of each target in the target solid model A target group, and select targets according to the edge intersection relationship between the targets in the A target group to form the B target group; track the targets in the B target group through a target tracking algorithm to obtain a moving target; count the moving targets , to obtain the traffic flow. The system includes an image acquisition module, a target three-dimensional model building module, an A target group acquisition module, a B target group acquisition module, a moving target acquisition module and a passenger flow statistics module.

Description

technical field [0001] The invention belongs to the field of passenger flow statistics, and more specifically relates to a method and system for passenger flow statistics based on binocular vision. Background technique [0002] At present, passenger flow statistics are mainly divided into the following three technologies: [0003] 1) Manual investigation of passenger flow [0004] Manual passenger flow surveys generally include on-board passenger flow surveys and on-site questionnaire surveys. The advantage is that the survey data is comprehensive. However, the survey process takes a long time, and the survey data is seriously lagging behind. Real-time statistics of passenger flow cannot be realized. [0005] 2) IC card passenger flow information collection [0006] In the public transport system, the IC card can store a large amount of passenger information, and the cost of using it to investigate passenger flow is very low. At present, ordinary residents in super-large ...
