Reference map acquisition method and device, equipment and storage medium

The invention provides a reference map acquisition method and device, equipment and a storage medium. The reference map acquisition method comprises the following steps: acquiring a plurality of sub-maps generated for different areas in a target scene; according to the map data corresponding to the plurality of sub-maps, determining scene information amount evaluation indexes corresponding to the plurality of sub-maps; according to the scene information amount evaluation index, a target sub-map is determined from the multiple sub-maps to serve as a reference map, and the reference map is a starting sub-map when the multiple sub-maps are spliced to generate the map of the target scene. In the scheme, the scene information amount corresponding to each sub-map is measured by setting the scene information amount evaluation index, so that the sub-map containing the most scene information amount can be screened out from the plurality of sub-maps based on the scene information amount evaluation index to serve as the
