摘要:
In a method of revising an unstable location fingerprint database for an area, a plurality of initial location fingerprint databases, comprising at least a stable location fingerprint database and an unstable location fingerprint database, are accessed. Signal measurement data is collected together with motion-based data from each of a plurality of portable devices transiting a portion of the area of the unstable location fingerprint database. Reference positions associated with locations in the unstable location fingerprint database are determined by using the stable location fingerprint database to process the collected signal measurement data and the motion-based data into the reference positions. The reference positions and the signal measurement data are employed to revise unstable data in the unstable location fingerprint database.
