The invention provides a railway vehicle limit measuring system. The system comprises a laser scanning module, a reference positioning module, a video acquisition processing module and a data source fusion calibration module, wherein the laser scanning module is installed at a front end of a vehicle body and comprises a laser contour sensor so as to measure basic contour data of a vehicle line limit through the laser scanning module, the reference positioning module is mounted on the vehicle body and comprises a positioning assembly, the positioning assembly is connected with the vehicle bodyto position the vehicle body, the video acquisition processing module is installed on the vehicle body so as to acquire images and / or the video information of obstacles along a vehicle track, , the laser scanning module, the reference positioning module and the video acquisition processing module are connected with the data source fusion calibration module, and all data measured by the laser scanning module, the reference positioning module and the video collecting and processing module are integrated through the data source fusion calibration module to obtain the limit of the railway vehicle.The system is advantaged in that a problem that in the prior art, measurement precision of the limit of the railway vehicle is low is solved.
Description
technical field [0001] The invention relates to the field of rail vehicle margin measurement, in particular to a rail vehicle margin measurement system. Background technique [0002] The margin refers to the contour dimension line that is not allowed to be exceeded by the rolling stock and the buildings and equipment close to the line in order to ensure the safety of the rolling stock running on the railway line and prevent the rolling stock from hitting the buildings and equipment adjacent to the line. [0003] At present, in the process of R&D and design of rail vehicles, because many railway lines have been put into use for decades or even longer, the relevant line boundary information and equipment boundary information are missing or incomplete, and the railway boundary needs to be re-investigated and measured , to provide accurate input for vehicle boundary design. [0004] There are two main types of existing line boundary measurement methods: [0005] One is to use ...
