The invention discloses a lane line recognition method and system and a vehicle, and the method comprises the steps: responding to the starting of an auxiliary driving mode, obtaining the image information of the surrounding environment of the vehicle in real time, and judging whether a shadow line parallel to a lane line exists in the image information or not; if yes, the current solar altitude is obtained, and the guardrail height of the guardrail, close to one side of the shadow line, of the vehicle is obtained from the image information; and judging whether the shadow line is a projection generated by the guardrail according to the solar altitude and the guardrail height, and if so, determining the shadow line as a non-lane line. According to the method, the lane is monitored in real time, when the shadow line parallel to the lane line appears on the lane, the current solar altitude and the guardrail height of the guardrail on the side where the shadow line appears are obtained, whether the shadow line is the projection generated by the guardrail or not is judged, if yes, the shadow line is determined to be a non-lane line, and if not, the shadow line is determined to be a non-lane line. Therefore, the vehicle can accurately identify the lane line and execute the auxiliary driving function, and the driving safety is improved.

    本申请公开了一种车道线识别方法、系统及车辆,车道线识别方法包括:响应于辅助驾驶模式的启动,实时获取车辆周边环境的图像信息,并在图像信息中判断是否存在与车道线并行的阴影线;若是,则获取当前的太阳高度角,并在图像信息中获取车辆靠近阴影线一侧护栏的护栏高度;根据太阳高度角以及护栏高度判断阴影线是否为护栏产生的投影,若是,则将阴影线确定为非车道线。本申请通过对车道进行实时监控,在车道上出现与车道线并行的阴影线时,获取当前的太阳高度角以及出现阴影线一侧护栏的护栏高度,并判断阴影线是否为护栏产生的投影,若是,则将阴影线确定为非车道线,以此达到车辆能够准确地识别出车道线并执行辅助驾驶功能,提高行车安全性。
