The invention relates to a rail transit obstacle detection method. The method comprises the steps that: a laser detection device is controlled to measure the rail width of each position of a rail in atarget area in the advancing direction of a rail transit train; the measured track width of each position of the track is compared with a train rail standard, so that calibration parameters corresponding to each position of the rail can be obtained; laser detection is continuously carried out on the target area to determine whether an obstacle exists in the target area; if the obstacle exists inthe target area, a first state of the obstacle is detected; and the first state is calibrated by using the calibration parameter of the rail position corresponding to the obstacle, so that a second state of the obstacle is obtained, and therefore, obstacle detection of rail transit can be realized. According to the method, the state of the detected obstacle is calibrated, so that the state of thedetected obstacle is more accurate, risk estimation can be carried out on a moving object with a collision risk, and the safety of rail transit during operation is guaranteed.

    本申请涉及一种轨道交通障碍探测方法,方法包括:控制激光探测装置对轨道交通列车前进方向目标区域内轨道各位置的轨道宽度进行测量;将测量得到的轨道各位置的轨道宽度与列车轨道标准宽度进行比对,得到轨道各位置对应的校准参数;对目标区域持续进行激光探测以确定目标区域是否存在障碍物;若目标区域存在障碍物,则探测障碍物的第一状态;利用障碍物对应轨道位置的校准参数对第一状态进行校准,得到障碍物的第二状态,从而实现对轨道交通的障碍探测。本方法通过对探测的障碍物的状态进行校准,从而使得探测的障碍物状态更为准确,且可以对存在碰撞风险的移动物体进行风险预估,保证了轨道交通运行时的安全性。
