System and method for indoor location mapping and tracking

摘要

Implementations of the present disclosure involve a system and/or method for indoor mapping. The indoor mapping system may receive wireless signals from wireless devices located in an area and create a wireless signal fingerprint that identifies each signal and the strength of the signal. A user may identify the location that the wireless signal fingerprint was taken on a geo-referenced map. After the wireless signal fingerprints for an area have been mapped, a user may determine a location by taking a wireless signal fingerprint and comparing the wireless signal fingerprint to previously taken wireless signal fingerprints.

主权项

1. A system for indoor mapping comprising:
at least one processor; an application executed by the at least one processor to:
receive a geo-referenced map;receive a first wireless signal fingerprint identifying a first set of present wireless signals and corresponding signal strengths for each wireless signal;receive a first user input identifying a first location on the geo-referenced map where the first wireless signal fingerprint was taken;upload the first location and the first wireless signal fingerprint to a mapping database;receive a second wireless signal fingerprint identifying a second set of present wireless signals and corresponding signal strengths for each wireless signal;receive a second user input identifying a second location on the geo-referenced map where the second wireless signal fingerprint was taken;upload the second location and the second wireless signal fingerprint to a mapping database;assign a reliability rating to each wireless signal fingerprint, wherein the reliability rating is incremented when:
the first location and the second location are within a threshold distance from each other; anda root mean square of the first wireless signal fingerprint and the second wireless signal fingerprint is greater than a similarity threshold.
