The invention belongs to the technical field of rail transit, and particularly discloses a steel rail crawling displacement detection system and method, and the detection system comprises a carrying platform, an imaging module, a data processing module and a measuring scale. The two measuring scales are arranged on the steel rail and the ballast bed, the imaging module is used for shooting the images of the measuring scales, the relative displacement of the measuring scales is calculated through an image processing algorithm, and the steel rail creeping value is calculated. Detection equipment is placed on the track inspection platform, only two measuring scales need to be arranged at the position of the steel rail, the method is more flexible and accurate, any number of detection points can be arranged at any position, the crawling condition of the steel rail can be comprehensively evaluated according to multiple data of the multiple measuring points, the method can also adapt to various complex environments such as bridges and tunnels, and the detection accuracy is improved. Through actual tests, the steel rail crawling displacement measurement precision reaches 0.1 mm.

    本发明属于轨道交通技术领域,具体公开了一种钢轨爬行位移检测系统及检测方法,该检测系统包含运载平台、成像模块、数据处理模块和测量标尺。本发明通过在钢轨及道床上设置两个测量标尺,利用成像模块拍摄测量标尺图像,通过图像处理算法计算测量标尺相对位移,计算钢轨爬行值。本发明将检测设备放置于轨道巡检平台上,只需在钢轨位置安置两个测量标尺,更为灵活、准确,且可在任意位置设置任意数量检测点,根据多个测量点的多个数据,综合评估钢轨的爬行情况,也能适应桥梁以及隧道等各种复杂的环境,通过实际测试,钢轨爬行位移测量精度达到了0.1mm。
