Indoor positioning using camera and optical signal

摘要

A method for detecting a collector device in an indoor area associated with imaging devices covering the area includes a plurality of collector devices emitting markers to the imaging devices coupled to a server. The imaging devices capture the images of the collector devices including the markers. The images are processed in order to determine the current positions of the collector devices corresponding to the markers. The server and the collector device communicate with each other and match a current position corresponding to the collector device among the plurality of collector devices.

1. A method for determining a location of a collector device associated with a server, a plurality of radio frequency (RF) signal sources and a plurality of imaging devices coupled to the server, the method comprising the collector device:
monitoring the multiple RF signal sources that are positioned in an indoor environment; collecting, by the collector device, multiple sets of measurements from the monitored multiple RF signal sources; determining a first position of the collector device based on the collected multiple sets of measurements; communicating information about the first position to the server; emitting a marker directly to one of the plurality of imaging devices, wherein the one imaging device is selected by the server, and the one imaging device is separate from the server; and receiving from the server, a second position that is mapped to the first position, in response to the marker; wherein the second position has higher precision than the first position.
