Lane line correction method and device, equipment and storage medium

The invention relates to a lane line correction method and device, equipment and a storage medium. The method comprises the steps of obtaining a to-be-corrected three-dimensional point of a to-be-corrected lane line and a three-dimensional point cloud of a real lane line corresponding to the to-be-corrected lane line; projecting the to-be-corrected three-dimensional point to a two-dimensional plane to obtain at least one to-be-corrected lane clue approach point, and projecting the three-dimensional point cloud to the two-dimensional plane to obtain a target image; performing feature extraction on the target image to obtain a feature map of the target image; extracting a feature block corresponding to each to-be-corrected lane clue approach point from the feature map, wherein each feature block at least comprises at least one target feature point of a real lane line; on the basis of the block features of the feature blocks corresponding to the to-be-corrected lane line leading points, the position of each to-b
