The invention discloses a self-adaptive obstacle avoidance early warning system and method for a running vehicle, a detection module is mounted at the front part of a vehicle body of the vehicle through a holder, and a central control unit controls the holder to rotate according to the running speed of the vehicle acquired by a vehicle speed sensor, so that the detection module faces the road surface along a set angle; the dot matrix light source emits light beams, and two-dimensional array light spots are formed on the road surface. The central control unit controls the camera to collect images of the two-dimensional light spot array in real time, distortion information of two-dimensional light spots is obtained, and therefore information of pits or protruding obstacles on the road surface is obtained through calculation; in the driving process, the vehicle driving speed is combined, the detection view field and the inclination angle of the detection module towards the road surface are adjusted in a self-adaptive mode, an alarm can be given once an obstacle exceeding a threshold value is detected, and therefore a driver is reminded, an intelligent vehicle can also actively decelerate through a detection result message, and the purpose of protecting the vehicle and pedestrians is achieved.

    本发明公开一种用于行驶车辆自适应避障预警系统及方法,探测模块通过云台安装在车辆的车身前部,中央控制单元根据车速传感器获取的车辆行驶速度,控制云台转动,使得探测模块沿设定的角度朝向路面;所述的点阵光源出射光束,且在路面上形成二维阵列光点;中央控制单元控制摄像头实时采集二维光点阵列图像,获取二维光点的畸变信息,从而计算得到路面凹坑或凸起障碍物的信息;本发明行驶过程中结合车辆行驶速度,自适应调整探测模块朝向路面的探测视场和倾角,一旦探测得到超出阈值的障碍物即可告警,从而达到提醒驾驶员,智能车辆也可以通过探测结果报文主动减速,起到保护汽车及行人的目的。
