Title:
DETECTION SYSTEM, METHOD AND APPARATUS FOR CROSS SECTION CONTOUR OF RAIL TRANSIT VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/067484
Kind Code:
A1
Abstract:
A detection system for a cross section contour of a rail transit vehicle. The system comprises: a target warning portal (10), which is arranged at a target detection position; a predetermined number of scanning devices (M1-Mn), which are arranged on the target warning portal (10) at predetermined intervals; a processing device (20); and a digital signal synchronization trigger (30), wherein the processing device (20) is used for acquiring, in real time and by means of each scanning device (M1-Mn), dynamic three-dimensional device coordinates of each detection point, corresponding to the scanning device (M1-Mn), on a cross section contour of a target vehicle in a three-dimensional device coordinate system of the scanning device (M1-Mn), and drawing, in a pre-defined three-dimensional reference coordinate system and on the basis of the dynamic three-dimensional device coordinates of each detection point, a cross section contour of the target vehicle at the moment when the target vehicle passes through the target warning portal (10). By means of the detection system, a determined cross section contour of a rail transit vehicle can be more accurate. Further provided are a detection method and apparatus for a cross section contour of a rail transit vehicle.
