The invention provides a lane line completion method and device, and relates to the technical field of electronic maps, and the method comprises the steps: obtaining lane line vector data corresponding to a map region to be subjected to lane line completion; according to the lane line vector data, determining a lane line image and a mapping relation between position coordinates of an original lane line in the lane line vector data and pixel point coordinates of the original lane line in the lane line image; according to the lane line image, determining a missing lane line and complementing the missing lane line to obtain a target lane line image; and according to the target lane line image and the mapping relation, determining the position coordinates of the complemented lane line after the missing lane line is complemented, and generating target lane line vector data. Therefore, the part with the missing lane line in the lane line vector data can be automatically complemented, compared with manual drawing complementation, the processing efficiency is greatly improved, and accurate complementation of the lane line in different map road scenes can be realized.

    本公开提供一种车道线补全方法及装置,涉及电子地图技术领域,方法包括:获取待进行车道线补全的地图区域所对应的车道线矢量数据;根据车道线矢量数据,确定车道线图像,以及车道线矢量数据中原始车道线的位置坐标与车道线图像中原始车道线的像素点坐标的映射关系;根据车道线图像,确定缺失车道线并进行补全,得到目标车道线图像;根据目标车道线图像和映射关系,确定缺失车道线补全后的补全车道线的位置坐标,生成目标车道线矢量数据。由此,能够对车道线矢量数据中存在缺失车道线的部分进行自动补全,相比于手工绘制补全,极大的提高处理效率,且能够实现在不同地图道路场景中进行车道线准确补全。
