The invention discloses a vehicle automatic driving safety distance control method, device and system and a storage medium. The method comprises the following steps: acquiring a first image and a second image; identifying a line beam in the second image and a second road marking closest to the vehicle, and judging the pose of the vehicle according to the position relationship between the second road marking and the line beam; identifying and judging a lane where the vehicle is located according to a first road marking in the first image; identifying the driving condition of the vehicle in front of the lane where the vehicle is located in the first image, and if there is a driving vehicle in front of the lane where the vehicle is located in the first image, acquiring the driving speed of the nearest vehicle in front of the lane; regulating the vehicle direction according to the vehicle pose so that the distance between the vehicle and the second road marking is larger than a threshold value, and adjusting the vehicle speed within the safe driving speed of the lane where the vehicle is located, so that the vehicle follows at the driving speed of the nearest vehicle in front of the lane where the vehicle is located. The safety of automatic driving can be improved.
本发明公开了一种车辆自动驾驶安全车距控制方法、装置、系统及存储介质,该方法包括以下步骤:获取第一图像和第二图像;识别第二图像中的线光束和与车辆距离最近的第二道路标线,根据第二道路标线和线光束的位置关系判断车辆位姿;识别并根据第一图像中的第一道路标线以判断车辆所在车道;识别第一图像中的车辆所在车道前方车辆行驶情况,若第一图像中车辆所在车道前方有行驶车辆,则获取车辆所在车道前方距离最近车辆的行驶速度;根据车辆位姿调整车辆方向使车辆与第二道路标线之间的距离大于一阈值,在所在车道安全行驶速度内调整车辆速度,以车辆所在车道前方最近车辆的行驶速度进行尾随。其可提高自动驾驶安全性。
