Abstract

The embodiment of the invention discloses a method and a system for measuring the height of a rail-side train part. The method of measuring the height of a rail-side train part comprises steps: a plane array camera is used to take a train image, wherein the train image comprises a train part image and a railway track image; a world coordinate system corresponding to the real space of the train andan image pixel coordinate system corresponding to the train image are built respectively, and coordinate corresponding parameters between the world coordinate system and the image pixel coordinate system are determined; according to the image pixel coordinate system, the pixel coordinates of the train part in the train image and the pixel coordinates of the railway track are acquired respectively; and according to the pixel coordinates of the train part, the pixel coordinates of the railway track and the coordinate corresponding parameters, the distance between the train part and the railwaytrack in the real space is calculated as the height of the train part. The technical scheme of the invention can realize accurate measurement on the height of the train part.

Description

technical field [0001] The invention relates to the technical field of train maintenance, in particular to a method and system for measuring the height of railside train components. Background technique [0002] With the development of the national economy, the flow of people and goods is gradually increasing, and the transportation burden and transportation speed of the train are also gradually increasing, which in turn leads to an increasing possibility of train parts failure. The possibility of train parts failure increases, which will seriously threaten the safe running of the train. Therefore, the inspection of train parts is very important to ensure the safety of train operation. [0003] In order to ensure the safe operation of trains, maintenance personnel usually need to carry out various inspections on trains, among which, the height measurement of train components (such as sand pipes, obstacle removers, stone sweepers and couplers) is an important part of train in...
