Fingerprint database updating method suitable for fingerprint positioning algorithm

摘要: The invention discloses a fingerprint database updating method suitable for positioning algorithm. comprises the steps of setting plurality calibrating APs which are usedfor and have unknown coordinates in area, reference points with known according to certain interval, acquiring signal strength value from each AP at point establishing database, performing acquisition by multiple times periods, statistics on number-of-times appearance signals non-calibrating APs, using exceeds preset threshold as an auxiliary AP; position coordinate adding information into finishing updating; wherein coordinate, network name AP. has advantages more conveniently quickly effectively ensuring high accuracy stability
