The invention discloses an automatic driving assistance method based on a 3D laser radar point cloud, and belongs to the technical field of driving assistance, and the method specifically comprises the steps: collecting point cloud data near a vehicle through a vehicle-mounted laser radar, and recognizing other vehicles and the distance Di and speed vi between the other vehicles and the vehicle after noise reduction; shape and size features of nearby vehicles and vehicle marks are extracted to judge the vehicle type, and then the fuel consumption value Oi is obtained; calculating the distance Li from each nearby vehicle to the next intersection by using a navigation system; the emission influence value Pi of each vehicle on the vehicle is calculated according to a formula, and if Pi is larger than a preset threshold value P0, the vehicle is reminded to be away from the vehicle; if Pi is smaller than or equal to P0, the vehicle with the highest emission absolute value Ti is screened and marked as Tmax, the safety distance SD is calculated, and a vehicle owner is prompted to keep the corresponding distance; according to the method, the types of nearby vehicles are identified based on the 3D laser radar point cloud, and the health of people in the vehicle is protected by detecting the high-emission vehicle.

    本发明公开了一种基于3D激光雷达点云的自动驾驶辅助方法,属于驾驶辅助技术领域,具体包括:通过车载激光雷达采集本车附近的点云数据,降噪处理后识别其他车辆及其与本车的距离Di和速度vi;提取附近车辆的形状、尺寸特征及车辆标志以判断车型,进而获取油耗值Oi;利用导航系统计算每台附近车辆距下个路口的路程Li;根据公式计算每台车辆对本车的排放影响值Pi,若Pi大于预设阈值P0则提示远离该车;若Pi均小于等于P0,则筛选排放绝对值Ti最高的车辆并标记为Tmax,计算出安全距离SD,提示车主保持相应距离;本发明基于3D激光雷达点云识别附近的车辆车型,通过对高排放车辆的检测,实现了对车内人员的健康的保护。
