The invention discloses a vehicle overtaking intelligent decision-making method and system based on image semantic recognition, and relates to the technical field of vehicle control, and the method comprises the steps: obtaining to-be-spliced images at different shooting angles around a vehicle through a vehicle-mounted sensor, controlling a feature detection region of the image through a mode of controlling a dynamic threshold value, and carrying out the feature detection of the to-be-spliced images; the method comprises the following steps: acquiring a vehicle surrounding environment image, obtaining first environment information by combining the edge of a target object, storing the first environment information in an overtaking lane-changing feature trainer to obtain a first lane line feature set, and judging whether a left lane and a right lane are lane-changing regions or not by setting a safe distance threshold value; after lane changing, the generated second environment information is input into the overtaking lane changing feature training device to obtain a second lane line feature set, and whether the original lane is a lane changing area or not is judged. The problems of low data detection efficiency in the overtaking process and poor scene understanding ability of non-visual perception in the field of intelligent overtaking of the automobile are solved, and overtaking lane changing errors caused by manual judgment are effectively reduced.
本发明公开了一种基于图像语义识别的车辆超车智能决策方法及系统,涉及车辆控制技术领域,该方法的步骤包括:通过车载传感器获取车辆周围不同拍摄角度的待拼接图像,通过控制动态阈值的方式控制图像的特征检测区域,获得车辆周围环境图像,结合目标物体边缘得到第一环境信息存储到超车变道特征训练器中得到第一车道线特征集合,通过设置安全距离阈值判断左右两车道是否为能变道区域,若能变道,变道后将生成第二环境信息输入超车变道特征训练器中得到第二车道线特征集合,判断原车道是否为能变道区域。本发明解决了在超车过程中数据检测效率低且非视觉感知在汽车在智能超车领域场景理解能力差的问题,有效减少人为判断的超车变道失误。
