Abstract
A method and an apparatus are disclosed for retrieving a 3D map by obtaining binary data of a plurality of 3D map descriptors, obtaining binary data of a retrieval descriptor, and performing retrieval in the binary data of the plurality of 3D map descriptors based on binary data of the retrieval descriptor, to obtain at least one target 3D map descriptor. The plurality of 3D map descriptors correspond to at least one 3D map point of the 3D map. The retrieval descriptor is a feature that corresponds to a real environment and that is extracted from visual information collected by a sensor of an electronic device. A length of binary data of each of the plurality of 3D map descriptors is different from a length of the binary data of the retrieval descriptor.
