Medical system indoor positioning error correcting method based on associated data mining

The invention belongs to the technical field of data mining and signal positioning and recognizing, and discloses a medical system indoor positioning error correcting method based on associated data mining. The medical system indoor positioning error correcting method based on associated data mining comprises the following specific steps: deploying at first; and then positioning. Particularly, according to deploying, a building with a single floor and m AP is measured and calculated to obtain signal feature data of the building, and the AP is hot spot; and according to positioning, a user determines a number of a measuring point (i) which is the closest to the position where the user is located at present. A zone boundary of a signal source is divided according to drift degree of a signalvector in different dimensions, and consistency of drift amplitude of different signal sources in the same region is considered to recognize the possible barrier movement condition. In a scene with lots of movable barriers in
