Subway vehicle door system V-shaped angle measuring method based on monocular vision

Abstract

The invention discloses a metro vehicle door system V-shaped angle measuring method based on monocular vision. The metro vehicle door system V-shaped angle measuring method comprises: obtaining an initial image, extracting an image datum point, solving a monocular vision camera parameter structure, and calculating the metro vehicle door system V-shaped angle. According to the invention, a monocular vision measurement technology is combined, remote real-time monitoring is carried out on V-shaped angle parameters of the metro vehicle passenger room door system, and monitoring and early warning are carried out on abnormal conditions of the door system, so that potential safety hazards existing in frequent opening and closing processes of the metro vehicle passenger room door system can be found timely and efficiently.

Description

technical field [0001] The invention relates to the technical field of rail transit detection, in particular to a method for measuring a V-shaped angle of a subway vehicle door system based on monocular vision. Background technique [0002] In order to speed up the development of cities and alleviate the increasing pressure on urban transportation, various places have vigorously built rail transit. Because the subway vehicle passenger compartment door system needs to be opened and closed frequently when the train runs to each station, the vehicle door system is prone to failure during use. According to statistics, the subway vehicle passenger compartment door system is the most prone to failure structure when the subway train is running one of the systems. Whether the design of the structural parameters of the passenger compartment door system of subway vehicles is reasonable, and whether the structural parameters of the door system change due to reliability problems such a...

AI Technical Summary

Problems solved by technology

As the service life of the train increases, the subway vehicle passenger compartment door system will be aged and worn to a certain extent. When the V-shaped angle of the subway vehicle door system changes beyond a certain limit, it will affect the switch of the subway vehicle passenger compartment door system and the airtightness of the compartment, etc. characteristics, even in severe cases will affect the normal operation of the entire train

Under the current situation, the fault diagnosis of the train door system mainly relies on manual detection, which has low efficiency and low detection quality, and the detection process is greatly affected by human subjective factors.
