Embodiment Construction
[0046] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0047] The method of the present invention is mainly divided into two stages: an offline stage and an online stage. In the offline stage, it mainly completes the fingerprint collection of wifi or bluetooth, and the marking of the electronic map; in the online stage, it completes three parts: rough fingerprint positioning, mobile mode determination, particle filter positioning and navigation.
[0048] Offline phase:
[0049] The first part, fingerprint information collection;
[0050] The second part, electronic map labeling.
[0051] Online phase:
[0052] The first part, wifi or bluetooth coarse positioning;
[0053] The second part, the mobile mode is determined, and the initial step size is set;
[0054] The third part, positioning and navigation.
[0055] The first part of the offline phase:
[0056] Fingerprint information collection. For g...
