The invention discloses a V2P anti-collision early warning method. The method comprises the following steps: step 1, receiving driving data of a vehicle and walking data of a pedestrian in a possible collision range of the vehicle and the pedestrian; 2, based on the scene that the pedestrian is located in the blind area of the driver of the vehicle, considering the uncertainty of the motion trail of the pedestrian and the position information error of the vehicle and the pedestrian, and establishing a human-vehicle anti-collision model; 3, predicting a pedestrian future trajectory by using an LSTM, obtaining a probability density function of the pedestrian trajectory in combination with the pedestrian trajectory obeying a multi-dimensional normal distribution function, and preliminarily deducing a collision area where the pedestrian collides with the vehicle; 4, calculating the confidence probability, and judging whether to give an early warning to pedestrians and vehicles or not according to the confidence probability; and step 5, repeating the step 1 to the step 4 until the vehicle and the pedestrian have no collision risk. The method can be applied to more general people and vehicle scenes, and has wide application potential in the fields of traffic safety, vehicle path planning, traffic management and the like.

    本发明公开了一种V2P防碰撞预警方法,包括:步骤1:接收车辆和行人可能发生碰撞范围内车辆的行车数据以及行人行进数据;步骤2:基于行人位于车辆驾驶员盲区场景,考虑行人运动轨迹的不确定性,车辆和行人位置信息误差,建立人‑车防碰撞模型;步骤3:利用LSTM对行人未来轨迹做出预测,结合行人轨迹服从多维正态分布函数得出行人轨迹的概率密度函数,初步推断行人与车辆发生碰撞的碰撞区域;步骤4:计算置信概率,利用置信概率判断是否对行人和车辆发出预警;步骤5:重复步骤1至步骤4,直至车辆和行人不存在碰撞风险。本发明可应用到更普遍的人车场景,在交通安全、车辆路径规划和交通管理等领域具有广泛的应用潜力。
