The invention discloses a collision risk early warning method for traffic vulnerable participants, and the main design conception of the method is as follows: two fisheye cameras with the visual field greater than 180 degrees are configured in front of a vehicle head and on one side of a blind area to fully cover images in front of and on the side of a vehicle; whether traffic vulnerability participants exist or not is accurately judged in cooperation with the visual perception and recognition technology, then early warning output is conducted on various different risk working conditions in combination with the vehicle speed, the gear and the relative relation between the target and the vehicle, and preferably, a grading early warning mechanism can be adopted; according to the invention, the driver is reminded to avoid risks in a refined manner in allusion to complex and changeable traffic scenes, so that the misrecognition of non-traffic vulnerability participating group targets is greatly reduced while low cost is taken into account, and the traffic safety is further improved.
本发明公开了一种针对交通弱势参与群体的碰撞风险预警方法,本发明的主要设计构思在于,通过在车头的正前方以及盲区一侧配置两颗视野大于180°的鱼眼摄像头全面覆盖车辆前方、侧方的影像,再配合视觉感知与识别技术准确分别是否存在交通弱势参与群体,之后结合车辆速度、挡位,以及目标与车辆的相对关系,对多种不同的风险工况进行预警输出,并且优选可以采用分级预警机制,实现针对复杂多变的交通情景精细化地提醒驾驶员避险,由此在兼顾较低成本的同时大大降低对非交通弱势参与群体目标的误识别,进而提升交通安全性。
