The invention relates to the technical field of intelligent transportation, in particular to the field of high-precision maps. The turn-around lane line automatic marking method provided by the embodiment of the invention comprises the following steps: acquiring information of an intersection entry point, information of an intersection exit point and information of an obstacle in a to-be-marked intersection; a U-turn lane line having a first depth is marked, the first depth being determined according to a second depth that the obstacle has. The first depth of the turn-round lane line is determined according to the second depth of the obstacle, so that the marked turn-round lane line cannot collide with the obstacle, a more proper turn-round lane line is marked, and the manual adjustment time is not needed or reduced.

    本申请涉及智能交通技术领域,更具体而言涉及高精度地图领域。本申请实施例提供的掉头车道线自动标注方法包括如下步骤:获取路口驶入点的信息、路口驶出点的信息和待标注路口内的障碍物的信息;标注具有第一深度的掉头车道线,该第一深度根据障碍物具有的第二深度来确定。通过根据障碍物具有的第二深度来确定掉头车道线的第一深度,能够使标注的掉头车道线不会与障碍物碰撞,而标注更适当的掉头用车道线,从而不需要或者减少人工调整的时间。
