The invention relates to the technical field of rail transit, in particular to a protection method and device for train driving safety. The second position information of the target obstacle can be determined based on the first position information, the scene image and the first point cloud data of the current train acquired in real time, and then the motion state information of the target obstacle in the future preset duration can be predicted based on the determined second position information of the target obstacle corresponding to the multiple moments, so that the target obstacle can be predicted more accurately. And further, on the basis of the motion state information of the target obstacle in the future preset duration, whether the current train and the target obstacle have a collision risk in the future preset duration can be determined, and if yes, the motion state of the current train is adjusted. In this way, the collision event between the current train and the obstacle can be effectively avoided, and the safety of rail transit can be improved.

    本申请涉及轨道交通技术领域,尤其涉及一种列车行驶安全的防护方法及装置。本申请基于实时获取当前列车的第一位置信息、场景图像和第一点云数据,可以确定出目标障碍物的第二位置信息,进而,基于确定出的多个时刻对应的目标障碍物的第二位置信息,可以预测目标障碍物在未来预设时长内的运动状态信息,进一步地,基于目标障碍物在未来预设时长内的运动状态信息,可以确定当前列车与目标障碍物在未来预设时长内是否存在碰撞危险,若存在,调整当前列车的运动状态。这样,可以有效避免当前列车与障碍物的碰撞事件的发生,可以提高轨道交通的安全性。
