Method for generating multi-source ubiquitous positioning fingerprint based on actually measured track

The invention discloses a method for generating a multi-source ubiquitous positioning fingerprint based on an actual measurement track, which comprises the following steps: determining the maximum value of a position uncertainty threshold range of the ubiquitous positioning fingerprint, generating an LF measurement value corresponding to a given AP point and an actual measurement track position point based on the given AP point and the actual measurement track position point, adding position uncertainty to the actual measurement track position point, and generating a multi-source ubiquitous positioning fingerprint. Various types of fingerprint data are generated by combining the two points, and the fingerprint data include but not limited to high-precision and low-density professional fingerprints acquired by robots and specially-assigned persons and consumer fingerprints which are acquired based on crowdsourcing tracks, semantic tracks and the like and are low in cost, wide in coverage and frequent in updati
