The invention discloses a vehicle collision judgment method and system, a terminal and a storage medium, and the method comprises the steps: obtaining the current sensor data of a vehicle when the change of a vehicle driving state is detected, and determining the corresponding track information according to the sensor data; if it is detected that the track information exists within the first preset time, determining speed information of the vehicle according to the track information; if it is judged that the speed information is larger than the preset value, the number of track points of the speed information is obtained, a speed variation result set is obtained according to the number of the track points, collision judgment is conducted on the vehicle according to the speed variation result set, and a vehicle collision result is obtained. According to the invention, collision detection is carried out by using the trajectory and speed data of the vehicle, and whether the vehicle is collided or not is judged by analyzing the speed change and trajectory crossing condition, so that a complicated machine learning algorithm is not needed, the real-time performance and accuracy of collision detection are improved, the dependence on a high-precision sensor is reduced, and the hardware cost is reduced.

    本发明公开了一种车辆碰撞的判断方法、系统、终端及存储介质,所述方法包括:当检测到车辆行驶状态发生变化时,获取车辆当前的传感器数据,并根据传感器数据确定对应的轨迹信息;若检测到第一预设时间内存在轨迹信息,则根据轨迹信息确定所述车辆的速度信息;若判定速度信息大于预设值,则获取速度信息的轨迹点数量,根据轨迹点数量得到速度变化量结果集,并根据速度变化量结果集对车辆进行碰撞判断,得到车辆碰撞结果。本发明通过利用车辆的轨迹和速度数据进行碰撞检测,并通过分析速度变化和轨迹交叉情况来判断车辆是否发生碰撞,无需复杂的机器学习算法,提高了碰撞检测的实时性和准确性,还减少了对高精度传感器的依赖,降低了硬件成本。
