Passenger path recognition method and passenger flow clearing method based on method

Abstract

The invention discloses a passenger path recognition method. The method comprises the following steps: acquiring monitoring videos of all subway passengers in all subway monitoring areas in a time period, wherein each frame of picture of the monitoring video comprises time information and space information; performing data cleaning operation on the monitoring video; the processed monitoring videois obtained; performing target extraction on each frame in the processed monitoring video by using a target detection algorithm; obtaining a face picture and a human body picture of each subway passenger in the frame; wherein the face picture of each subway passenger in all frames corresponding to each subway monitoring area in the monitoring video forms a face picture set of the subway monitoringarea, and the human body picture of each subway passenger in all frames corresponding to each subway monitoring area in the monitoring video forms a human body picture set of the subway monitoring area. According to the invention, the technical problems of time and labor consuming and low clearing efficiency of the existing manual account-dividing clearing method can be solved.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and more specifically relates to a passenger path identification method and a passenger flow sorting method based on the method. Background technique [0002] The subway has assumed an increasingly important role in modern urban transportation. Millions of people choose the subway to travel every day, and the complexity of the subway network is getting higher and higher. In the daily production and operation of the subway, different sections often involve different operators, but because the travel trajectory of passengers is closely related to the interests of different operators, this makes passenger flow clearing a very important systematic Work. [0003] The existing passenger flow sorting methods mainly include: a manual sorting method and a sorting method based on passenger travel paths. The method of manual accounting and clearing is to evaluate the assets of each rail...

Problems solved by technology

[0005] Aiming at the above defects or improvement needs of the prior art, the present invention provides a passenger route identification method and a passenger flow sorting method based on the method, the purpose of which is to solve the need for manual processing of the existing manual sorting method, which leads to time-consuming Due to the technical problems of time-consuming and low sorting efficiency, and the existing sorting method based on the passenger travel path, the number of data samples in the statistical model based on probability is low, and the adjustment period of the model parameters is long, resulting in the number of passengers calculated by the model. There is a certain error between the travel route distribution and the actual travel route of passengers, which in turn affects the technical problem of the accuracy of sorting
