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,
