SYSTEM AND METHOD FOR INDOOR GEOLOCATION AND MAPPING

摘要

Methods and systems to provide location and navigation information to a user within a building. In an embodiment, low power radars may be used to locate and track a user. Moreover, the systems and methods described herein may take advantage of the known layout of a building, or may ascertain the layout using the radar devices. This information may be used to direct a user from a current location to a desired destination. In some contexts, such as stores, radio frequency ID (RFID) tags may be used to identify a particular destination, such as a particular product in a particular aisle in a store. Multiple persons may be tracked as they move about the building, so that the more frequently used paths may be identified for moving from point to point. These identified paths may then be used in constructing a path for a user who needs directions.
