The invention relates to a vehicle collision early warning method and device, which are used for integrally controlling vehicles with collision risks on a road surface. The method comprises the following steps that: multiple pieces of road section vehicle information acquired by road monitoring equipment of a road section at different acquisition moments are acquired; for the same vehicle in the multiple pieces of road section vehicle information, predicted positions of the vehicle at N future moments is predicted according to position information of the vehicle in the multiple pieces of road section vehicle information; for any future moment, the canvas position of each vehicle in a two-dimensional canvas is determined according to the predicted position of each vehicle at the future moment, so that the collision prediction of each vehicle at the future moment is obtained, wherein the two-dimensional canvas is generated according to a map of the road section; and according to the collision prediction of each vehicle at the N future moments, the vehicle with the collision possibility is determined.

    一种车辆碰撞预警方法及装置,用以整体掌控路面上存在碰撞风险的车辆。所述方法包括:获取路段的道路监测设备在不同采集时刻采集的多个路段车辆信息;针对所述多个路段车辆信息中的同一车辆,根据所述车辆在所述多个路段车辆信息中的位置信息,预测所述车辆在N个未来时刻的预测位置;针对任一未来时刻,根据各车辆在所述未来时刻的预测位置,确定各车辆在二维画布中的画布位置,从而得到各车辆在所述未来时刻的碰撞预测;所述二维画布是根据所述路段的地图生成的;根据各车辆在N个未来时刻的碰撞预测,确定存在碰撞可能性的车辆。
