Method and device for measuring wheel steering angle of intelligent rail train

Abstract

The invention relates to a method and device for measuring the steering angle of wheels of an intelligent rail train. Based on the measurement method, an embedded processor, a bracket, a camera and atarget are utilized; the wheel steering angle can be efficiently measured; the hinging disc angle during train alignment can be efficiently calculated; the defects that an existing measuring method iscomplex in process, difficult to operate and large in measuring error are overcome through four-eye vision of the camera, rapid angle measurement, angle calibration and the like can be achieved, andthen deviation, drifting, inconsistent two-way driving performance and the like in the vehicle driving process are guided and improved.

Description

technical field [0001] The invention relates to a rail transit system, in particular to a method and a measuring device for measuring the steering angle of a wheel of an intelligent rail train. Background technique [0002] Compared with the traditional low-to-medium volume rail transit system, the smart rail train is a new type of transportation that combines the advantages of modern trams and buses. It has a short construction period, small infrastructure investment, high urban adaptability, and comprehensive transport capacity. Strong and other advantages have brought new choices and experiences to solve travel difficulties in large and medium-sized cities. The use of "virtual track following technology" allows trains to follow the lines on the ground. Smart rail trains or "virtual rail trains" seem to have no rails, but actually have "rails". Smart devices are not installed on the rails, but on the train, the road runs along the imaginary rails drawn on the ground or def...

Problems solved by technology

[0006] The main purpose of the present invention is to provide a method for measuring the wheel steering angle of an intelligent rail train, through four-eye or multi-eye vision imaging, wheel target recognition and wheel steering angle calculation, to solve the problem of existing measurement methods in other fields. The shortcomings of numerous processes, difficult operation, and large measurement errors can realize rapid angle measurement and angle calibration, etc., thereby improving problems such as deviation, tail flicking, and inconsistent two-way driving performance during vehicle driving.
