Abstract

The invention discloses a method and a system for automatically detecting the state of a train apron board based on computer vision. The method comprises the steps that at least two parallel color strips coated with specified colors are arranged on each apron board in advance, at least two parallel color strips coated with specified colors are arranged on the side wall, provided with the apron boards, of a vehicle body in advance, and the long edges of the color strips on the apron boards and the long edges of the color strips on the side wall of the vehicle body are perpendicular to apron board rotating shafts; images of the apron board and the side wall of the vehicle body are collected, color bars on the apron board and the side wall of the vehicle body are recognized in the images, and the apron board rotation angle is calculated according to the color bar recognition result. According to the invention, the included angle between the apron board and the side wall of the train can be measured in a non-contact manner, so that dangerous situations such as loosening and even falling of the apron board can be early warned in advance.

Description

technical field [0001] The invention belongs to the technical field of automatic detection, and more particularly, relates to an automatic detection method for the state of an EMU skirt board based on computer vision. Background technique [0002] The skirt panel of the high-speed rail EMU, also known as the fully enclosed equipment compartment, is a baffle arranged on both sides of the lower body of the high-speed rail EMU. EMU skirts can protect the car body and equipment, guide the airflow inside and outside the car, and facilitate maintenance personnel to view key equipment. During the high-speed operation of the EMU, vibration will occur, and other adverse factors will cause the apron to become loose, which not only makes the original function of the apron lose, but also may endanger the safety of passengers and railway staff. Skirt for overhaul. [0003] At present, the relevant departments need to arrange a special person to check the status of each group of skirt p...
