针对我国现有轨道爬行及路基冻融引起的钢轨高低检测技术的不足，提出一种基于机器视觉及光学成像原理的钢轨爬行及路基表层冻胀的非接触式检测技术。根据检测技术原理建立光学模型，基于模板匹配、自动化阈值、图像形态学处理等图像处理方法，通过硬件系统实现对钢轨爬行及路基表层冻胀引起的钢轨高低位移的测量，并经由 GPRS 无线通讯技术将数据实时传输至 WEB 数据服务器，可以实现对检测数据的实时监控管理。在哈大高铁 K186＋600及 K148＋600两点安装设备进行验证性试验，试验结果表明，该技术可定点定时采集钢轨实时图像，自动检测钢轨相对“零点”时刻的爬行数据及路基表层冻胀数据，并在爬行或路基表层冻胀数据超限时自动报警，指导铁路养护作业。

A non -touching detection technology of rail crawl and surface subgrade frost heaving was proposed based on machine vision &optical imaging principle aiming at the shortcomings of the rail height detection tech-nology for the frost heave of rail.The equipment processes image by methods of template matching,automatic thresholding,image mathematical morphology processing and so on,based on the principle of optical imaging. Transfer the real -time date back to the WEB data server through the GPRS wireless communication technology. The equipment can improve the operation safety of railway in cold area.
