This application relates to the field of intelligent transportation technologies, and more specifically, to the field of high-definition maps. A provided method for automatically marking a U-turn lane line includes the following steps: obtaining information about an intersection entry point, information about an intersection exit point, and information about an obstacle at a to-be-marked intersection; and marking a U-turn lane line with a first depth. The first depth is determined based on a second depth of the obstacle. The first depth of the U-turn lane line is determined based on the second depth of the obstacle, so that a marked U-turn lane line does not collide with the obstacle, to mark a more proper U-turn lane line. Therefore, a manual adjustment time is not implemented or is reduced.
