Pavement arrow vector element creation method, apparatus, medium, device, and program

The invention discloses a pavement arrow vector element manufacturing method and device, a storage medium, equipment and a program product, and belongs to the technical field of high-precision maps. The method comprises the following steps: projecting a road surface point cloud in a predetermined rectangular area which is pre-collected by a collection vehicle and takes a current track point of the collection vehicle as a center to a bird's-eye view angle plane where the current track point is located to obtain a projection point cloud picture; generating a point cloud intensity graph according to the point cloud reflection intensity of the point cloud in the projection point cloud graph; identifying road surface arrow elements in the point cloud intensity graph to obtain positions of the road surface arrow elements in the point cloud intensity graph; and obtaining the position of the road surface arrow element in the world coordinate system by utilizing the position and attitude conversion matrix of the curre
