The invention provides a vehicle door opening collision early warning method. The method comprises the following steps: acquiring distance information between a vehicle and a road sill; acquiring current vehicle door terrain clearance information of the vehicle; under the condition that the distance between the vehicle and the road sill is smaller than or equal to the length of a vehicle door of the vehicle, acquiring shooting position information of a reference object on the vehicle and height information of the road sill through image acquisition equipment, a reference object on the vehicle is located in an imaging range of the image acquisition equipment and has a height difference with the image acquisition equipment; determining the actual height information of the road sill based on the shooting position information of the reference object on the vehicle and the height information of the road sill; and under the condition that the actual height of the road sill is larger than the current vehicle door ground clearance of the vehicle, an alarm message is sent to the vehicle. Therefore, the actual height of the road sill can be more accurately determined on the basis of the reference object, early warning is performed on the basis of the comparison result with the actual ground clearance of the vehicle door, and the quality of early warning information is improved.
本发明提供了一种车辆开门碰撞预警方法,包括:获取车辆与路槛的距离信息;获取所述车辆当前的车门离地高度信息;在所述车辆与所述路槛的距离小于或等于所述车辆的车门长度的情况下,通过图像采集设备获取所述车辆上参照物的拍摄位置信息和所述路槛的高度信息,所述车辆上参照物处于所述图像采集设备的成像范围且与所述图像采集设备存在高度差;基于所述车辆上参照物的拍摄位置信息和所述路槛的高度信息,确定所述路槛的实际高度信息;在所述路槛的实际高度大于所述车辆当前的车门离地高度的情况下,向所述车辆发出告警消息。这样,可以基于参照物更准确地确定路槛实际高度,并基于与车门实际离地高度的对比结果作出预警,提高预警信息的质量。
