The invention relates to the technical field of speed measurement, and provides a rail train speed measurement method and device, and the method comprises the steps: carrying out the clustering of the relative speed between a train and each target point, which is measured by a millimeter wave radar on the train at a current frame, and obtaining a group to which each relative speed belongs; screening all the groups according to the acceleration of the train and the final speed of the previous frame measured by an accelerometer on the train between the previous frame of the current frame and the current frame; and determining the final speed of the train in the current frame according to the relative speeds in the screened groups. The accuracy and reliability of train speed measurement are improved, and maintenance is convenient.

    本发明涉及速度测量技术领域,提供一种轨道列车测速方法及装置,该方法包括:对列车上的毫米波雷达在当前帧测量的所述列车与每个目标点之间的相对速度进行聚类,获取每个相对速度所属的分组;根据所述列车上的加速度计在所述当前帧的前一帧到所述当前帧之间测量的所述列车的加速度和所述前一帧的最终速度,对所有分组进行筛选;根据筛选的所述分组中的相对速度,确定所述列车在所述当前帧的最终速度。本发明提高列车测速的准确性和可靠性,便于维护。
