The invention provides a collision risk identification method and device, electronic equipment and a storage medium. The method comprises the following steps: determining a predicted motion track of an obstacle according to position data of the obstacle; according to the predicted motion trail of the obstacle and the outer contour point cloud data of the vehicle, whether the obstacle has a collision risk to the vehicle is judged; determining a predicted collision point between the obstacle and the vehicle from the predicted movement track of the obstacle under the condition that the obstacle has the collision risk to the vehicle; and determining a danger coefficient of the obstacle according to the predicted collision point. According to the invention, the predicted collision point is determined according to the predicted movement track of the obstacle and the outer contour point cloud data of the vehicle, the predicted collision point can be accurately and rapidly determined, and the accuracy and efficiency of collision risk identification are improved. Besides, the danger coefficient of the obstacle is determined based on the predicted collision point, so that the danger of the obstacle is quantified, and support is provided for making safer and more reasonable driving decisions for subsequent vehicles.

    本发明提供了一种碰撞风险识别方法、装置、电子设备及存储介质,该方法包括:根据障碍物的位置数据确定障碍物的预测运动轨迹;根据障碍物的预测运动轨迹和车辆的外轮廓点云数据,判断障碍物对车辆是否有碰撞风险;在障碍物对车辆有碰撞风险的情况下,从障碍物的预测运动轨迹中确定障碍物和车辆之间的预测碰撞点;根据预测碰撞点确定障碍物的危险系数。本发明通过根据障碍物的预测运动轨迹和车辆的外轮廓点云数据去确定预测碰撞点,能够准确且快速地确定出预测碰撞点,提高了碰撞风险识别的准确率和效率。另外,通过基于预测碰撞点确定障碍物的危险系数,实现了对障碍物的危险性进行量化,为后续车辆做出更安全、更合理的驾驶决策提供了支持。
