Bus passenger traffic statistical method based on stereoscopic vision and system therefor

Abstract

The invention discloses a bus passenger movement statistics method and system based on stereo copy. It adopts stereo copy apparatus and algorithm. The stereo copy image collector is positioned on the top of the bus door to real time collect the passenger on-and-off image; the controller adopts stereo copy algorithm to process the two eyes image to obtain the image depth information and obtain the passenger head location, size and grey information by compounding the single eye image processing information; then the following part dose real time following with the passenger head information to obtain the number of the on-and-off passengers so as to obtain the passenger movement information.

Description

Technical field: [0001] The invention relates to bus passenger flow statistics, in particular to a method and system for bus passenger flow statistics based on stereo vision. Background technique: [0002] In recent years, public places such as exhibition halls, stadiums, libraries, airports, subways and buses have installed intelligent monitoring and dispatching systems. For these systems, the importance of real-time and accurate passenger flow information is self-evident. At present, the main means of passenger flow information statistics are infrared occlusion system and pressure sensor system. The advantages of these two traditional methods are simple implementation and low cost, but their main disadvantages are inaccurate statistics, and they are powerless to solve the congestion situation during peak passenger flow. [0003] Compared with other information, the capacity of image information is larger and richer. Therefore, the rise and continuous development of image p...

AI Technical Summary

Problems solved by technology

[0004] 1) The background changes complexly with the light, which is not conducive to the extraction of the foreground (human head);

[0005] 2) In the case of peak passenger flow congestion, people are closely connected, and the method based on two-dimensional information is difficult to accurately distinguish several people who are crowded together, and the crowding situation is very frequent;

[0006] 3) Due to the existence of the steps of the bus, the head of the same person appears to change in size from the monocular camera at a fixed position when getting on and off the bus, which is very unfavorable for recognition and tracking
