In a fusion positioning method based on a multi-type map, an electronic device obtains a target image to be positioned, and obtains a target location at which the target image is photographed. The device determines, in a map database including a plurality of different types of map data, target map quality of a map located at the target location, and a target positioning manner from a plurality of different preset positioning manners based on the target map quality. The target positioning manner includes a basic positioning manner corresponding to each piece of map data included in the map database. The device then positions the target image in the target positioning manner to obtain a 6 degree of freedom (6DOF) of the target image.
