Trigger regions
A method includes receiving, from a subscriber device, a request including virtual region characteristics and an occupancy threshold, and determining, using image data captured by a camera and the virtual region characteristics, a virtual region corresponding to a portion of a physical region within a field of view of the camera. The virtual region is smaller than the physical region. The method also includes determining, using the image data, an occupancy of the virtual region and determining that the occupancy of the virtual region satisfies the occupancy threshold. In response to determining that the occupancy of the virtual region satisfies the occupancy threshold, the method also includes generating a notification to the subscriber device.
1. A computer-implemented method when executed by data processing hardware causes the data processing hardware to perform operations comprising:
receiving, from a subscriber device, a request comprising virtual region characteristics and an occupancy threshold, the virtual region characteristics specifying a region of interest for the subscriber device;
determining, using image data captured by a camera and the virtual region characteristics, a virtual region corresponding to a portion of a physical region within a field of view of the camera, the virtual region in the field of view of the camera and smaller than the physical region within the field of view of the camera;
determining, using the image data, an occupancy of the virtual region;
determining that the occupancy of the virtual region satisfies the occupancy threshold; and
in response to determining that the occupancy of the virtual region satisfies the occupancy threshold, generating a notification to the subscriber device.
2. The method of claim 1 , wherein the virtual region characteristics comprises one or more attributes, the one or more attributes comprising at least one of:
a size of the virtual region;
a shape of the virtual region;
a relative location of the virtual region within the physical region; or
a relative orientation of the virtual region within the physical region.
3. The method of claim 1 , determining the virtual region comprises using image data captured by a plurality of cameras.
4. The method of claim 1 , wherein determining the occupancy of the virtual region comprises determining a number of people within the virtual region.
5. The method of claim 1 , wherein the operations further comprise:
determining that an actor has occupied the virtual region for at least a threshold period of time; and
in response to determining that the actor has occupied the virtual region for at least the threshold period of time, generating a second notification to the subscriber device.
6. The method of claim 1 , wherein the operations further comprise:
determining that a physical change has occurred within the virtual region; and
in response to determining that the physical change has occurred within the virtual region, generating a second notification to the subscriber device.
7. The method of claim 1 , wherein the operations further comprise:
determining a number of actors that enter the virtual region; and
generating a second notification to the subscriber device, the second notification comprising the number of actors that enter the virtual region.
8. The method of claim 1 , wherein the notification comprises a time that the occupancy of the virtual region satisfied the occupancy threshold.
9. The method of claim 1 , wherein the operations further comprise:
receiving, from the subscriber device, a second request comprising updated virtual region characteristics; and
updating the virtual region based on the updated virtual region characteristics.
10. The method of claim 1 , wherein the portion of the physical region that the virtual region corresponds to is dynamic.
11. A system comprising:
data processing hardware; and
memory hardware in communication with the data processing hardware, the memory hardware storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations comprising:
receiving, from a subscriber device, a request comprising virtual region characteristics and an occupancy threshold, the virtual region characteristics specifying a region of interest for the subscriber device;
determining, using image data captured by a camera and the virtual region characteristics, a virtual region corresponding to a portion of a physical region within a field of view of the camera, the virtual region in the field of view of the camera and smaller than the physical region within the field of view of the camera;
determining, using the image data, an occupancy of the virtual region;
determining that the occupancy of the virtual region satisfies the occupancy threshold; and
in response to determining that the occupancy of the virtual region satisfies the occupancy threshold, generating a notification to the subscriber device.
12. The system of claim 11 , wherein the virtual region comprises one or more attributes, the one or more attributes comprising at least one of:
a size of the virtual region;
a shape of the virtual region;
a relative location of the virtual region within the physical region; or
a relative orientation of the virtual region within the physical region.
13. The system of claim 12 , determining the virtual region comprises using image data captured by a plurality of cameras.
14. The system of claim 11 , wherein determining the occupancy of the virtual region comprises determining a number of people within the virtual region.
15. The system of claim 11 , wherein the operations further comprise:
determining that an actor has occupied the virtual region for at least a threshold period of time; and
in response to determining that the actor has occupied the virtual region for at least the threshold period of time, generating a second notification to the subscriber device.
16. The system of claim 11 , wherein the operations further comprise:
determining that a physical change has occurred within the virtual region; and
in response to determining that the physical change has occurred within the virtual region, generating a second notification to the subscriber device.
17. The system of claim 11 , wherein the operations further comprise:
determining a number of actors that enter the virtual region; and
generating a second notification to the subscriber device, the second notification comprising the number of actors that enter the virtual region.
18. The system of claim 11 , wherein the notification comprises a time that the occupancy of the virtual region satisfied the occupancy threshold.
19. The system of claim 11 , wherein the operations further comprise:
receiving, from the subscriber device, a second request comprising updated virtual region characteristics; and
updating the virtual region based on the updated virtual region characteristics.
20. The system of claim 11 , wherein the portion of the physical region that the virtual region corresponds to is dynamic.
