Abstract
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.
