Systems and methods for locating devices in venues
In an embodiment, the present invention is a device locationing system operable to dynamically determine the presence of keep-out zones within a venue, and thereafter adjust positional data obtained through the device based on the presence of the previously detected keep-out zones.
1. A locationing system for use within a venue, the locationing system comprising:
a plurality of sensors disposed within the venue, each of the plurality of sensors configured to provide a data stream at least partially representative of a movement of at least one object on at least a portion of a floor of the venue;
a server communicatively connected to the plurality of sensors, the server configured to generate a floor map of the venue based at least in part on the data stream from each of the plurality of sensors, the floor map including a plurality of keep-out zones;
a plurality of ultrasonic transmitters disposed within the venue, each of the ultrasonic transmitters configured to emit an auditory signal; and
a mobile device communicatively coupled to the server, the mobile device being configured to detect the auditory signal emitted by at least one of the ultrasonic transmitters, the mobile device being further configured to transmit signal data related to a detection of the auditory signal emitted by at least one of the ultrasonic transmitters to the server,
wherein the server is further configured to provide positional data of the mobile device based at least in part on the signal data and based at least in part on the floor map.
2. The locationing system of claim 1 , wherein each of the plurality of sensors includes a video camera, and wherein the data stream includes a video stream capturing the movement of the at least one object along a respective path.
3. The locationing system of claim 2 , wherein the plurality of keep-out zones is based at least in part on areas outside of the at least some of the respective paths.
4. The locationing system of claim 1 , wherein the at least one object includes at least one of a person or a cart.
5. The locationing system of claim 1 , wherein the server is further configured to update the floor map based at least in part on the data stream from each of the plurality of sensors.
6. The locationing system of claim 1 , wherein the floor map is at least one of a logical floor map or a graphical floor map.
7. The locationing system of claim 1 , wherein the server is further configured to generate the floor map of the venue based in part on a predefined floorplan.
8. A method of locating a mobile device within a venue, the method comprising:
disposing a plurality of sensors within the venue, each of the plurality of sensors configured to provide a data stream at least partially representative of a movement of at least one object on at least a portion of a floor of the venue;
communicatively connecting a server to the plurality of sensors, the server configured to generate a floor map of the venue based at least in part on the data stream from each of the plurality of sensors, the floor map including a plurality of keep-out zones;
disposing a plurality of ultrasonic transmitters within the venue, each of the ultrasonic transmitters configured to emit an auditory signal;
communicatively coupling the mobile device to the server, the mobile device being configured to detect the auditory signal emitted by at least one of the ultrasonic transmitters, the mobile device being further configured to transmit signal data related to a detection of the auditory signal emitted by at least one of the ultrasonic transmitters to the server; and
providing, via the server, positional data of the mobile device based at least in part on the signal data and based at least in part on the floor map.
9. The method of claim 8 , wherein each of the plurality of sensors includes a video camera, and wherein the data stream includes a video stream capturing the movement of the at least one object along a respective path.
10. The method of claim 9 , wherein the plurality of keep-out zones is based at least in part on areas outside of the at least some of the respective paths.
11. The method of claim 8 , wherein the at least one object includes at least one of a person or a cart.
12. The method of claim 8 , wherein the server is further configured to update the floor map based at least in part on the data stream from each of the plurality of sensors.
13. The method of claim 8 , wherein the floor map is at least one of a logical floor map or a graphical floor map.
14. The method of claim 8 , wherein the server is further configured to generate the floor map of the venue based in part on a predefined floorplan.
