The invention relates to a collision risk assessment method and device, and the method comprises the steps: obtaining the reference path information of a vehicle at the current moment, and enabling the reference path information to be used for indicating reference path points and the timestamp of the vehicle reaching each reference path point; acquiring displacement information of a first interaction object, wherein the displacement information is used for indicating the displacement passed by the first interaction object under the timestamp of each reference path point; obtaining a relative motion path of the vehicle relative to the first interaction object based on the reference path information and the displacement information; and determining whether there is a collision risk between the vehicle and the first interaction object according to the relative motion path. According to the collision risk assessment method provided by the embodiment of the invention, the collision risk of the current behavior of the vehicle can be accurately and quickly assessed.

    本申请涉及一种碰撞风险评估方法及装置,所述方法包括:获取当前时刻自车的参考路径信息,所述参考路径信息用于指示参考路径点以及自车到达每个所述参考路径点的时间戳;获取第一交互对象的位移信息,所述位移信息用于指示所述第一交互对象在每个所述参考路径点的时间戳下所经过的位移;基于所述参考路径信息和位移信息得到所述自车相对于第一交互对象的相对运动路径;根据所述相对运动路径确定所述自车与所述第一交互对象之间是否存在碰撞风险。本申请实施例提供的碰撞风险评估方法能够准确、快速地评估车辆当前行为的碰撞风险。
