IMAGE ASSISTANCE FOR INDOOR POSITIONING

摘要

A method for tracking collector devices in an indoor area associated with imaging devices and RF signal sources covering the area includes generating aspects of a plurality of coarse position tracks of the collector devices based on RF signal measurements obtained by the collector devices from the RF signal sources. Imaging devices capture image frames of the collector devices in the indoor area which are then processed in order to determine aspects of a plurality of fine position tracks of the collector devices. The server and the collector device communicate with each other and match aspects of at least one of the fine position tracks to the aspects of the coarse position track of the communicating collector device in order to determine the precise location of the collector device in the indoor area.

1. A method for determining a fine position of a collector device associated with a server and a plurality of imaging devices coupled to the server, the method comprising the collector device:
collecting multiple sets of sensor measurements from at least one sensor associated with the collector device; determining at least aspects of a coarse position track based on the multiple sets of sensor measurements; receiving from the server at least respective one of the aspects of a plurality of fine position tracks imaged by the imaging devices; and determining the fine position of the collector device by matching at least the aspects of the coarse position track to the aspects of at least one of the fine position tracks.
