The invention discloses a pedestrian collision prediction method and system. The method comprises the steps: obtaining a pedestrian position under a vehicle body coordinate system, a pedestrian movement direction under the vehicle body coordinate system and a pedestrian movement state under the vehicle body coordinate system from perspective transformation video information through a deep learningmethod; determining a driving area of the vehicle based on pre-acquired vehicle parameters and mapping the driving area to the perspective transformation video information to obtain a driving area under a vehicle body coordinate system, and determining the position of the pedestrian relative to the driving area based on the driving area and the pedestrian position; and predicting whether the pedestrian collides with the vehicle based on the position of the pedestrian relative to the driving area of the vehicle, the pedestrian movement direction and the pedestrian movement state, and if a preset collision condition is met, determining that the pedestrian collides with the vehicle. According to the scheme, the orientation and the motion trend of the pedestrian are recognized in real time, and the driving area of the vehicle is calculated in advance so that whether the pedestrian collides with the vehicle or not is accurately predicted, and pedestrian collision prediction accuracy is improved.

    本发明公开了一种行人碰撞预测方法及系统,利用深度学习方法从透视变换的视频信息中得到车体坐标系下的行人位置、车体坐标系下的行人运动朝向和车体坐标系下的行人运动状态,基于预先获取的车辆参数确定车辆的行驶区域并映射到透视变换的视频信息中,得到车体坐标系下的行驶区域,基于行驶区域和行人位置,确定行人相对于行驶区域的位置,基于行人相对于车辆的行驶区域的位置、行人运动朝向和行人运动状态预测行人是否与车辆发生碰撞,若符合预设碰撞条件,确定行人与车辆发生碰撞。通过上述方案,对行人进行朝向和运动趋势进行实时识别,并且提前计算出车辆的行驶区域,从而准确预测出行人是否会与车辆发生碰撞,提高对行人碰撞预测的准确性。
