The invention relates to a lane line generation method and system. The method comprises the following steps that: an image containing a lane line collected during the driving of a vehicle and geographical position information of the vehicle are acquired; the image is identified, pixel coordinates of pixel points of a lane line in the image can be obtained; according to the pixel coordinates of thelane lines and the corresponding geographic position information, space coordinates of the two lane lines of a lane where the vehicle is located currently are obtained through calculation; whether the space coordinates of the two lane lines are stored or not is searched; if the space coordinates of the two lane lines are not stored, the space coordinates of the lane lines are stored; and for thelane lines with the stored space coordinates, space coordinate optimization processing is performed on the lane lines according to a preset rule. According to the method and system provided of the technical schemes provided by the invention, the lane lines required by a high-precision map can be manufactured based on video data and positioning signals acquired by the single vehicle. The method andsystem have the advantages of low manufacturing cost, short processing flow, simple algorithm and high efficiency, and greatly shorten the manufacturing and updating period of the high-precision map.

    本申请是关于一种车道线生成方法及系统。所述方法包括,获取车辆行驶中采集的包含车道线的图像以及车辆的地理位置信息;对所述图像进行识别,得到所述图像中的车道线像素点的像素坐标;根据所述车道线的像素坐标和对应的所述地理位置信息,计算得到车辆当前所在车道的两条车道线的空间坐标;查找是否已保存了该两条车道线的空间坐标;若未保存,则保存该车道线的空间坐标;对于已保存空间坐标的车道线,按照预置的规则进行车道线的空间坐标优化处理。本申请提供的方案,可基于单一车辆采集的视频数据和定位信号进行高精地图所需车道线的制作,具有制作成本低、处理流程短、算法简单、效率高的特点,大大缩短了高精地图的制作及更新周期。
