The invention provides a train wheel set motion state detection method and device. The method comprises the steps that a three-dimensional laser contour scanner on a train is used for obtaining point cloud data of a steel rail where a train wheel set is located; extracting feature points of the steel rail from the point cloud data based on a Hough transform method; and determining the motion state of the feature point based on a Newton iteration method, and determining the motion state of the wheel set of the train according to the motion state of the feature point. The motion state of the train wheel set is accurately detected, the detection equipment and method are simple, the detection efficiency is improved, and the detection cost is reduced.

    本发明提供一种列车轮对运动状态检测方法及装置,该方法包括:使用列车上的三维激光轮廓扫描仪获取列车的轮对所在处钢轨的点云数据;基于霍夫变换方法从所述点云数据中提取所述钢轨的特征点;基于牛顿迭代法确定所述特征点的运动状态,根据所述特征点的运动状态确定所述列车的轮对的运动状态。本发明准确检测列车轮对的运动状态,且检测设备和方法简单,提高检测效率,降低检测成本。
