The invention relates to a vehicle collision early warning method and system, and the method comprises the following steps: obtaining an environment image in front of a vehicle in real time in the current driving process of the vehicle, and recognizing an early warning target from the current frame image; acquiring a transverse distance and a longitudinal distance of the early warning target at the current moment according to the current frame image; obtaining the longitudinal collision time of the early warning target; obtaining the transverse movement distance of the early warning target in the longitudinal collision time corresponding to the current moment; and according to the transverse distance of the vehicle at the current moment and the transverse movement distance within the longitudinal collision time corresponding to the current moment, whether the safety driving requirement is met between the current vehicle and the early warning target or not is judged. According to the invention, accurate and rapid collision prediction can be carried out on the transverse target so as to ensure the driving safety of the vehicle.

    本发明涉及一种车辆碰撞预警方法及系统,其包括如下步骤:当前车辆行驶过程中,实时获取车辆前方的环境图像,并从当前帧图像中识别出预警目标;根据当前帧图像获取预警目标在当前时刻下的横向距离以及纵向距离;获取预警目标的纵向碰撞时间;获取预警目标在与当前时刻对应的纵向碰撞时间内的横向运动距离;根据车辆在当前时刻下的横向距离,以及与当前时刻对应的纵向碰撞时间内的横向运动距离判断当前车辆与预警目标之间是否满足安全行驶要求。本发明可以对横向上的目标进行准确、迅速的碰撞预测,以保证车辆行驶安全。
