The invention provides a driving obstacle early warning method and system. The method comprises the following steps that S1, whether a height limiting facility exists in front of a driving route of a vehicle or not is determined; s2, if it is determined that a height limiting facility exists in front of the driving route of the vehicle, the height limiting height of the height limiting facility is determined through a visual technology or pre-stored data; s3, comparing the limited height with the height of the vehicle; and S4, if the height of the vehicle exceeds the height limit height, giving an alarm, and determining and displaying distance information of the height limit facility relative to the vehicle. According to the driving obstacle early warning method and system, the height limiting height of the height limiting facility does not need to be measured through a traditional distance measuring technology, operation of the driving obstacle early warning method and system is not limited by the sensing range of a height measuring device, operation can be achieved when the distance between the vehicle and the height limiting facility is far enough, and therefore the driving obstacle early warning method and system have higher safety and practicability compared with the prior art.
本申请提供一种行车障碍预警方法及系统,所述方法包括以下步骤:S1,确定车辆的行驶路线的前方是否存在限高设施;S2,如果确定所述车辆的行驶路线的前方存在限高设施,则通过视觉技术或者预存数据确定所述限高设施的限高高度;S3,将所述限高高度与所述车辆的高度进行比较;S4,若所述车辆的高度超出所述限高高度,则发出警报,并确定和显示所述限高设施相对于所述车辆的距离信息。所述行车障碍预警方法及系统不需要用传统的测距技术测出限高设施的限高高度,其操作不会受到高度测量装置的感测范围的限制,在车辆距离限高设施足够远的时候就可以实现,因此相比于现有技术具有更高的安全性和实用性。
