DEVICE AND A METHOD FOR DETECTING DEFECTS ON THE EXTERIOR OF A RAILWAY VEHICLE, CAPABLE OF RAPIDLY RECOGNIZING THE DEFECT EXISTENCE OF THE EXTERIOR OF THE RAILWAY VEHICLE

摘要

PURPOSE: A device and a method for detecting defects on the exterior of a railway vehicle are provided to periodically scan the exterior of the railway vehicle with a laser radar sensor and judge the defect existence by comparing scanned images with exterior images of the normal railway vehicle.;CONSTITUTION: A device(100) for detecting defects on the exterior of a railway vehicle comprises a laser radar sensor(110), an image processing unit(120), a determination unit(130), and a display unit(140). The laser radar sensor is installed in both side-wall surfaces of the inside of a tunnel, an upper wall surface and a rail. The laser radar sensor scans the exterior of the railway vehicle, thereby generating signals. The image processing unit receives the signals generated in the laser radar sensor, thereby forming images. The determination unit confirms whether the images are coincided with an exterior image of the normal railway vehicle or not. The display unit displays a result determined by the determination unit in an engine room.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Laser radar sensor; (120) Image processing unit; (130) Determination unit; (140) Display unit; (150) Storage unit; (160) Communication unit
