Lane line label generation method and device, equipment and storage medium

The invention relates to the technical field of intelligent driving, and discloses a lane line label generation method and device, equipment and a storage medium. The lane line label generation method comprises the following steps: generating local point cloud data of different position areas based on road surface information collected by a vehicle-mounted sensor; based on the local point cloud data, constructing a high-precision map of the global region; acquiring lane line information of the current vehicle and surrounding lane line information from the high-precision map; and outputting the lane line information as a lane line label in a corresponding content format based on the training requirement of the deep learning model. According to the method, a mode of automatically generating the lane line labels from the high-precision map is adopted, and the lane line labels can be used for multiple times through one-time labeling, so that the lane line labeling efficiency and labeling speed are improved, and m
