Method and device for calculating passenger vehicle passenger flow congestion degree

Abstract

The invention provides a method and a device for calculating a passenger vehicle passenger flow congestion degree. The method comprises steps that images respectively acquired by at least two cameras in a passenger vehicle are acquired, the acquired images are spliced to form a panorama image in the passenger vehicle, body identification and counting are carried out on the basis of the panorama image, and the counting result is used for carrying out passenger vehicle passenger flow analysis. The method is advantaged in that the images acquired by the multiple cameras are spliced according to an image coordinate transformation matrix, the panorama image in the vehicle is determined, body detection of the panorama image in the vehicle is carried out to determined the quantity of passengers in the vehicle, the passenger vehicle passenger flow congestion degree is analyzed according to the passenger quantity detected from the panorama image but not according to statistics on the basis of accumulation difference of passengers getting on and off of vehicle gates, an accumulation error is avoided, and statistics precision is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of bus passenger flow detection, and in particular to a method and device for calculating the passenger flow congestion degree of passenger cars. Background technique [0002] The urban public transportation system is an important part of the urban transportation system. It has the advantages of small environmental pollution, collective management, large transportation volume, energy saving and road space saving. Therefore, major cities at home and abroad have successively adopted bus priority, bus Measures such as special lanes, and then promote the information intelligence construction of urban public transportation; and how the vehicle management department obtains the passenger flow data of vehicles under its jurisdiction in a timely and accurate manner determines whether it can reasonably arrange routes and optimize dispatching plans. At present, there are many methods for vehi...
