The invention provides a collision risk determination method and device. The collision risk determination method comprises the steps of: collecting radar data and video data through a radar and a camera respectively; performing alignment processing on the radar data and the video data; fusing the aligned radar data and video data based on the weight features of the radar data and the weight features of the video data, and determining obstacle height information and obstacle azimuth information; and determining vehicle collision risk information based on a vehicle chassis height, the obstacle height information and the obstacle azimuth information. According to the collision risk determination method and device provided by the invention, the radar data and the video data are matched and fused based on the weight features of the radar data and the video data, and the obstacle height information and the obstacle azimuth information are determined according to the fusion result, so that the vehicle collision risk information is obtained, and the confidence is more objective; the accuracy of collision risk determination can be improved.

    本申请提供一种碰撞风险确定方法和装置,所述碰撞风险确定方法包括:通过雷达和摄像头分别采集雷达数据和视频数据;对所述雷达数据和所述视频数据进行对齐处理;基于所述雷达数据的权重特征和所述视频数据的权重特征,对经过对齐处理的所述雷达数据和所述视频数据进行融合,确定障碍物高度信息和障碍物方位信息;基于车辆底盘高度、所述障碍物高度信息以及所述障碍物方位信息,确定车辆碰撞风险信息。本申请提供的碰撞风险确定方法和装置,通过对雷达数据和视频数据进行匹配,并基于两者的权重特征进行融合,根据融合结果确定障碍物高度信息和障碍物方位信息,从而得到车辆碰撞风险信息,使得置信度更加客观,能够提升对碰撞风险确定的准确度。
