The invention relates to a method and equipment for detecting longitudinal displacement of a seamless track steel rail, and belongs to the technical field of steel rail detection. The longitudinal displacement detection device comprises a hand-push type support which is used for being arranged on a steel rail and providing support for other modules; the camera module is used for capturing image information of a displacement observation pile and an observation scale on the steel rail; and the centralized control module is used for collecting, processing and transmitting data. A second industrial personal computer configured by the centralized control module is configured to perform illumination adjustment on image data acquired in real time by the camera module in the process of moving along with the hand-push type bracket by using a deep learning algorithm to ensure that an image is clear; centroid coordinates of the observation pile and the observation scale are calculated through an edge detection and contour extraction algorithm; and comparing the images acquired in real time with the images in the basic database, calculating the longitudinal displacement of the steel rail, and updating the database.

    本发明涉及一种无缝线路钢轨纵向位移检测方法及设备,属于钢轨检测技术领域。该纵向位移检测设备包括手推式支架,用于布设在钢轨上并为其他模块提供支撑;相机模块,用于捕捉钢轨上的位移观测桩和观测标尺的图像信息;集中控制模块,用于实现数据的收集、处理和传输。集中控制模块配置的第二工控机被配置为:使用深度学习算法对相机模块在跟随手推式支架移动的过程中实时采集的图像数据进行光照调节,确保图像清晰;通过边缘检测和轮廓提取算法计算观测桩及观测标尺的形心坐标;对比实时采集的图像与基础数据库中的图像,计算钢轨的纵向位移,并更新数据库。
