The invention discloses a track ground object profile detection method, which comprises the following steps of: installing a comprehensive detection system comprising a one-dimensional laser displacement sensor below a train, aligning to a to-be-identified ground object, and detecting a series of point coordinates measured by the one-dimensional laser displacement sensor when the train runs, the method comprises the following steps: acquiring a fluctuating square wave track in the running direction of a train, comparing pre-stored profiles of ground objects through the track according to different vertical distances, and counting the quantity and shape related parameters of the ground objects, so as to realize the automatic detection of the profiles of the ground objects. According to the method, the defects of low recognition speed and poor universality in the prior art are overcome, and the railway line ground object profile can be quickly recognized.

    本发明公开了一种轨道地面物廓型检测方法,将包含一维激光位移传感器的综合检测系统安装于列车下方,并对准待识别地面物,当列车走行时,由一维激光位移传感器测出的一系列点坐标,获得一条列车走行方向上的高低起伏的方波轨迹,根据垂向距离不同,通过轨迹对比地面物预存廓型,统计出地面物的的数量、形状相关参数,从而实现地面物廓型自动检测。本发明解决了现有技术识别速度慢、通用性差的缺陷,可实现铁路线路地面物廓型的快速识别。
