Abstract

In one embodiment, one or more computing devices receive an identifying feature of a target entity, the identifying feature requiring that the target entity to be in a line of sight of a camera for the camera to recognize the identifying feature; locate the target entity using the camera based on the identifying feature; and track the target entity using the camera based on the identifying feature.

Claims

1. A method comprising:

by one or more computing devices, receiving an identifying feature of a target entity, the identifying feature requiring that the target entity to be in a line of sight of a camera for the camera to recognize the identifying feature;

locating the target entity using the camera based on the identifying feature; and

tracking the target entity using the camera based on the identifying feature.

2. The method of claim 1, wherein the identifying feature is a Radio-Frequency Identification (RFID) tag associated with the target entity.

3. The method of claim 1, wherein the identifying feature is a radio signal associated with the target entity.

4. The method of claim 1, further comprising determining a current location of the target entity.

5. The method of claim 1, further comprising relocating the target entity using the camera based on the identifying feature after the camera loses track of the target entity.

6. The method of claim 1, wherein:

the target entity is one of a plurality of entities in a vicinity of the camera; and

one or more of the entities are moving entities.

7. A system comprising:

a memory comprising instructions executable by one or more processors; and

the one or more processors coupled to the memory and operable to execute the instructions, the one or more processors being operable when executing the instructions to;

receive an identifying feature of a target entity, the identifying feature requiring that the target entity to be in a line of sight of a camera for the camera to recognize the identifying feature;

locate the target entity using the camera based on the identifying feature; and

track the target entity using the camera based on the identifying feature.

8. The system of claim 7, wherein the identifying feature is a Radio-Frequency Identification (RFID) tag associated with the target entity.

9. The system of claim 7, wherein the identifying feature is a radio signal associated with the target entity.

10. The system of claim 7, wherein the processors are further operable when executing the instructions to determine a current location of the target entity.

11. The system of claim 7, wherein the processors are further operable when executing the instructions to relocate the target entity using the camera based on the identifying feature after the camera loses track of the target entity.

12. The system of claim 7, wherein:

the target entity is one of a plurality of entities in a vicinity of the camera; and

one or more of the entities are moving entities.

13. One or more computer-readable non-transitory storage media embodying software operable when executed by one or more computer systems to:

receive an identifying feature of a target entity, the identifying feature requiring that the target entity to be in a line of sight of a camera for the camera to recognize the identifying feature;

locate the target entity using the camera based on the identifying feature; and

track the target entity using the camera based on the identifying feature.

14. The media of claim 13, wherein the identifying feature is a Radio-Frequency Identification (RFID) tag associated with the target entity.

15. The media of claim 13, wherein the identifying feature is a radio signal associated with the target entity.

16. The media of claim 13, wherein the software is further operable when executed by the computer systems to determine a current location of the target entity.

17. The media of claim 13, wherein the software is further operable when executed by the computer systems to relocate the target entity using the camera based on the identifying feature after the camera loses track of the target entity.

18. The media of claim 13, wherein:

the target entity is one of a plurality of entities in a vicinity of the camera; and

one or more of the entities are moving entities.

19. A system comprising:

means for receiving an identifying feature of a target entity, the identifying feature requiring that the target entity to be in a line of sight of a camera for the camera to recognize the identifying feature;

means for locating the target entity using the camera based on the identifying feature; and

means for tracking the target entity using the camera based on the identifying feature.
