The invention discloses an obstacle detection method and system for a rail transit vehicle. Comprising the steps that a first image in front of a vehicle within a first preset distance range is obtained, a second image in front of the vehicle within a second preset distance range is obtained, wherein the maximum distance to the vehicle in the second preset distance range is larger than the maximum distance to the vehicle in the first preset distance range, and the minimum distance to the vehicle in the second preset distance range is smaller than or equal to the maximum distance to the vehicle in the first preset distance range; and according to the first image and/or the second image, an obstacle existing in the vehicle clearance is detected, and warning information is sent out. The invention comprises acquiring an image in front of a vehicle within a first preset distance range and an image in front of the vehicle within a second preset distance range, and detecting whether an obstacle exists in the vehicle clearance according to the images acquired from the two distance ranges, wherein the second preset distance range can be a distance range far away from the vehicle. Therefore, the invention can remotely detect obstacles and can be used for vehicles with high running speeds.
本发明公开了一种轨道交通车辆的障碍物检测方法及系统,获取车辆前方第一预设距离范围内的第一图像以及获取车辆前方第二预设距离范围内的第二图像,第二预设距离范围中到车辆的最大距离大于第一预设距离范围中到车辆的最大距离,第二预设距离范围中到车辆的最小距离小于等于第一预设距离范围中到车辆的最大距离,根据第一图像和/或第二图像,检测出存在于车辆限界内的障碍物并发出警示信息。本发明获取车辆前方第一预设距离范围内的图像以及第二预设距离范围内的图像,根据从两个距离范围获取的图像检测车辆限界内是否有障碍物,第二预设距离范围可以是距离车辆较远的距离范围,因此本发明能够远距离地探测障碍物,能够用于较高行驶速度的车辆。
