description The invention discloses a wireless local area network (WLAN) indoor positioning method based on overlapping of two sets of fingerprints, and belongs to the technical field of wireless communication. The WLAN indoor positioning method based on overlapping of the two sets of fingerprints is used for positioning the indoor personnel/asset in a WLAN environment. According to the method, signal features of reference points are firstly collected in an off-line period, and a first RSS fingerprint database is built; position coordinates of all the reference points in the first fingerprint database are translated, the two sets of fingerprints intersect and are overlapped, then the signal features of the translated reference points are collected, and a second RSS fingerprint database is built. In an on-line positioning period, grid positions of a point to be positioned in two fingerprint maps are judged respectively, an average value of the grid center point coordinates is obtained, and positioning is carried out; if t
