The invention discloses a train speed measurement positioning method, device and equipment and a storage medium, and the method comprises the steps: obtaining a plurality of scanning points and a scanning image composed of the plurality of scanning points, and determining a fitting straight line of the scanning point for each scanning point, the scanning point being obtained by scanning an environment through a laser sensor arranged on a train, or the fitting straight line being obtained by scanning the environment through the laser sensor arranged on the train; scanning by a laser sensor arranged in a train running environment; according to the fitting straight line corresponding to each scanning point, determining a feature point from each scanning point; and determining the displacement of the feature point between two adjacent frames of scanning images to obtain a train speed measurement positioning result. According to the technical scheme, off-line mapping is not needed, calculation of train speed measurement and positioning is achieved in real time, and calculation complexity is reduced.
本发明公开了一种列车测速定位方法、装置、设备及存储介质,包括:获取多个扫描点和由所述多个扫描点组成的扫描图像,针对每个扫描点,确定所述扫描点的拟合直线,其中,所述扫描点为设置在列车上的激光传感器扫描环境得到,或者,由设置在列车行驶环境上的激光传感器扫描得到;根据各扫描点所对应的拟合直线,从各所述扫描点中确定出特征点;确定所述特征点在相邻两帧扫描图像之间的位移,得到列车测速定位结果。上述技术方案,无需离线建图,实时实现列车测速定位的计算,降低计算复杂度。
