Abstract
A method, apparatus, and computer readable storage medium for updating an electronic map are disclosed. A method for updating an electronic map includes: acquiring a group of collected images collected by a collection entity and associated with a target map element in the electronic map, the target map element having a target image and a target location; executing inter-group matching between the group of collected images and the target image; executing intra-group matching among the group of collected images; and updating a location of a to-be-updated map element associated with the target map element based on the inter-group matching, the intra-group matching and the target location. In this way, the positioning precision of map elements can be improved.
