The invention provides a vehicle and pedestrian collision early warning method and device. The method comprises the following steps: constructing a vehicle entity model of a vehicle and a pedestrian entity model of a pedestrian; acquiring a vehicle course angle of the vehicle, a pedestrian course angle of the pedestrian, a vehicle speed of the vehicle and a pedestrian speed of the pedestrian in an east-north-sky coordinate system; determining at least one collision critical point according to the vehicle entity model and the pedestrian entity model, and determining a collision critical point coordinate value of the collision critical point according to the vehicle course angle, the pedestrian course angle, the vehicle speed and the pedestrian speed; and performing collision early warning on the vehicle and the pedestrian according to the collision critical point coordinate value and a preset early warning judgment rule. According to the invention, the false alarm rate can be reduced while the pedestrian safety is ensured.
本发明提供了一种车辆与行人碰撞预警方法及装置,其方法包括:构建车辆的车辆实体模型和行人的行人实体模型;获取在东北天坐标系中的所述车辆的车辆航向角、所述行人的行人航向角、所述车辆的车辆速度以及所述行人的行人速度;根据所述车辆实体模型和所述行人实体模型确定至少一个碰撞临界点,并根据所述车辆航向角、所述行人航向角、所述车辆速度和所述行人速度确定所述碰撞临界点的碰撞临界点坐标值;根据所述碰撞临界点坐标值以及预设的预警判断规则对所述车辆与所述行人进行碰撞预警。本发明可在确保行人安全性的同时降低误报率。
