System and method of personalized navigation inside a business enterprise
First Claim
1. A system for tracking locations of individuals in a building, the system comprising:
- at least one radiofrequency (RF) node disposed near an entrance to the building, the at least one RF node having an RF receiver to receive RF signals from RF-transmitting devices near the entrance to the building;
at least one optical device disposed near the entrance to the building, the at least one optical device capturing an image of a plurality of persons while the plurality of persons is near the entrance to the building; and
a controller in communication with the at least one RF node to obtain therefrom information associated with the RF signals received by the RF receiver of that at least one RF node and in communication with the at least one optical device to obtain therefrom the captured image,the controller being configured to determine an identity of each RF-transmitting device and an angular position of that RF-transmitting device with respect to each RF node of the at least one RF node based on the information associated with the RF signals obtained by the controller from that RF node of the at least one RF node,the controller being further configured to detect a plurality of humans in the image obtained by the controller from the at least one optical device, to detect in the image an orientation marker, and to assign the identity of each RF-transmitting device to one of the plurality of humans detected in the image based on a position of the orientation marker in the image relative to each human detected in the image and on the determined angular position of that RF-transmitting device with respect to each RF node of the at least one RF node, thereby identifying each individual who is to be located optically as that individual moves throughout the building.

Abstract
Systems and methods for tracking movement of individuals through a building receive, by one or more RF nodes disposed near an entrance to the building, RF signals from RF-transmitting mobile devices carried by persons near the entrance, capture an image of the persons while they are near the entrance, determine an identity and relative distance of each RF-transmitting mobile device from each RF node based on information associated with the RF signals received by that RF node, detect humans in the image, determine a relative depth of each human in the image, and assign the identity of each RF-transmitting mobile device to one of the humans detected in the image based on the relative distance of each RF-transmitting mobile device from each RF node and the relative depth of each human in the image, thereby identifying each individual who to be tracked optically as that individual moves throughout the building.

10. A method for tracking locations of individuals in a building, the method comprising:
-
receiving, by at least one radiofrequency (RF) node disposed near an entrance to the building, RF signals from RF-transmitting mobile devices carried by a plurality of persons near the entrance to the building; capturing an image of the plurality of persons while the plurality of persons is near the entrance to the building; determining an identity of each RF-transmitting mobile device and an angular position of each RF-transmitting mobile device from each RF node based on information associated with the RF signals received by the at least one RF node; detecting a plurality of humans and an orientation marker in the captured image; assigning the identity of each RF-transmitting mobile device to one of the plurality of humans detected in the captured image based on a position of the orientation marker in the image relative to each human detected in the image and on the determined angular position of each RF-transmitting mobile device with respect to each RF node, thereby identifying each individual who is to be located optically as that individual moves throughout the building. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
