Abstract
A computer-implemented method for building a 3D map, includes: obtaining plural videos and plural video-related data units, each of the plural video-related data units indicating a feature of radio wave signals received at a place where a corresponding video has been taken; reconstructing plural 3D models, respectively, based on the plural videos; selecting a pair of 3D models from the plural 3D models based on similarity between a corresponding pair of video-related data units; and merging the pair of 3D models to obtain the 3D map.
