Method for generating and positioning indoor multi-source ubiquitous positioning fingerprint database

The invention provides a method for generating and positioning an indoor multi-source ubiquitous positioning fingerprint database, and the method achieves the effective fusion of ubiquitous positioning fingerprints with different precisions through the position uncertainty corresponding to the measurement value of a positioning fingerprint signal (LF), and achieves the construction and positioning of the ubiquitous positioning fingerprint database. Due to the fact that carriers, devices, collecting modes and the like used for collecting indoor positioning fingerprints are different, errors exist in measured values, the positions of reference points in a clustered database are wrongly matched with the measured values of positioning fingerprint signals, and finally the positioning result is affected. The invention constructs a new database construction and positioning method based on the influence, completes the construction and positioning of the ubiquitous positioning fingerprint database by using the positio
