Structured light-based high-speed detection system and method for railway fastener

A structured light-based high-speed detection system and a method for railway fasteners belongs to the technical field of optical detection, and the system comprises: a high-speed camera, a laser source, and a processing system, wherein the laser source and the high-speed camera are respectively disposed at the upper part of a fastener region to be detected, and emit respectively a set of structured light to the region of the fastener; the high-speed camera photographs the image of the fastener region; the high-speed camera is connected to the processing system and the image is transferred; the processing system performs image treatment and determines to obtain the detected results. The invention solves the defects of low identification speed and poor generality in the prior art, is applicable to the on-line rapid detection of railway steel rail fastener loss, and has the advantages of high identification speed, good generality, and strong adaptability.
