The invention relates to a detection method and device for looseness of a rail fastener. The detection method comprises the following steps: carrying out real-time shooting by a high-speed industrialcamera along with the advancing of a vehicle; transmitting shot images to a data processor through a data transmission line, and processing and analyzing the image by the data processor by adopting adeep learning algorithm, wherein the processing analysis comprises the following steps: comparing the processed image with a stored standard image, outputting a comparison result in the form of a report, and if a fastener is loosened, performing calculation according to the acquired train speed and the frame number of the image to obtain the accurate position of an abnormal fastener. According tothe rail fastener looseness detection method and device provided by the invention, looseness detection can be effectively carried out on the track fastener, and meanwhile, abnormities such as missingand bounce-stop breakage of the fastener can be detected.

    本发明涉及一种用于轨道扣件松动的检测方法及装置,所述检测方法包括:高速工业相机随机车的行进进行实时拍摄,拍摄的图像通过数据传输线传至数据处理器,数据处理器采用深度学习的算法将图像进行处理分析,处理分析包括:将处理后的图像与存储的标准图像进行比对,比对结果以报表的形式输出,如果扣件出现松动,将通过采集到的列车速度和图像的帧数进行计算,得出异常扣件的准确位置。本发明提供的轨道扣件松动的检测方法和装置,能够有效的对轨道扣件进行松动检测,同时也能检测出扣件的缺失和弹停断裂等异常。
