Abstract

Methods and systems for providing a single stream including multiple FoVs. One system includes an image sensor configured to receive a selection of a plurality of field-of-views from a user, capture an image associated with each of the plurality of field-of-views, stitch the image associated with each of the plurality of field-of-views into a single stream, and transmit the single stream to at least one computing device.

First claim

What is claimed is:

1. A system for providing an image stream, the system comprising:
an image sensor configured to
receive a selection of a plurality of field-of-views made by a user,
capture a video image associated with each of the plurality of field-of-views, wherein at least two of the plurality of field-of-views differs in time,
automatically apply a configuration policy based on at least one of a video analytic algorithm and an alarm-based field-of-view policy, the video analytic algorithm selected from a group consisting of people counting, motion detection and activation of a physical alarm within a current field-of-view, the configuration policy configured to adjust image size of each of the plurality of field-of-views, wherein the image size associated with the current field-of-view has a larger size than one or more of other field-of-views;
stitch the video image associated with each of the plurality of field-of-views into a single stream, and
transmit the single stream to at least one computing device.

2. The system of claim 1 , wherein the image sensor includes a first sensor and a second sensor and wherein the image sensor is configured to capture a video image of one of the plurality of field-of-views using the first sensor and capture a video image of another one of the plurality of field-of-views using the second sensor.

3. The system of claim 2 , wherein the first sensor includes an optical sensor and the second sensor includes a thermal sensor.

4. The system of claim 1 , wherein the image sensor is further configured to apply at least one of a manual configuration mode and an automatic configuration mode to the plurality of field-of-views.

5. The system of claim 4 , wherein, in applying the manual configuration mode, the image sensor receives configuration parameters from the user for at least one of the plurality of field-of-views.

6. The system of claim 5 , wherein the configuration parameters include at least one selected from the group comprising an image size for at least one of the plurality of field-of-views, an aspect ratio for at least one of the plurality of field-of-views, a refresh rate for at least one of the plurality of field-of-views, a resolution for the stitched stream, and a refresh rate for the stitched stream.

7. The system of claim 5 configured to have the user set a parameter selected from a group consisting of a zoom, a focus mode, an iris mode, a thermal parameter, and a white balance associated with the image sensor.

8. The system of claim 1 , wherein, in applying the automatic configuration mode, the image sensor automatically specifies configuration parameters for each of the plurality of field-of-views, wherein the configuration parameters include at least one selected from the group comprising an image size for at least one of the plurality of field-of-views, an aspect ratio for at least one of the plurality of field-of-views, and a refresh rate for at least one of the plurality of field-of-views.

9. The system of claim 8 , wherein, in applying the automatic configuration mode, the image sensor automatically specifies identical configuration parameters for each of the plurality of field-of-views.

10. The system of claim 1 , further comprising the computing device, wherein the computing device is configured to receive the selection from the user and display the stitched stream to the user within a single frame.

11. The system of claim 1 , wherein the stitched stream includes a description for a video image for one of the plurality of field-of-views.

12. The system of claim 1 , wherein one of the plurality of field-of-views representing the current field-of-view is highlighted within the stitched stream.

13. The system of claim 1 , wherein a video image associated with one of the plurality of field-of-views is associated with the current field-of-view and appears larger in the stitched stream.

14. The system of claim 1 , wherein video images associated with at least two of the plurality of field-of-views differ in time.

15. A method of providing an image stream, the method comprising:
receiving, by a processing unit, a selection of a plurality of field-of-views made by a user;
capturing, by the processing unit, a video image associated with each of the plurality of field-of-views, wherein at least two of the plurality of field-of-views differs in time;
applying, by the processing unit, a configuration policy based on at least one of a video analytic algorithm and an alarm-based field-of-view policy, the video analytic algorithm selected from a group consisting of people counting, motion detection and activation of a physical alarm within a current field-of-view, the configuration policy including adjusting image size of each of the plurality of field-of-views, wherein the image size associated with the current field-of-view has a larger size than one or more of other field-of-views;
stitching, by the processing unit, the video image associated with each of the plurality of field-of-views into a single stream; and
transmitting the single stream to at least one computing device.

16. The method of claim 15 , wherein capturing the video image associated with each of the plurality of field-of-views includes capturing a video image of one of the plurality of field-of-views using an optical sensor and capturing a video image of one of the plurality of field-of-views using a thermal sensor.

17. The method of claim 15 , further comprising receiving configuration parameters, by the processing unit, made by a user.

18. The method of claim 17 , wherein receiving the configuration parameters includes receiving at least one selected from the group comprising an image size for at least one of the plurality of field-of-views, an aspect ratio for at least one of the plurality of field-of-views, a refresh rate for at least one of the plurality of field-of-views, a resolution for the stitched stream, and a refresh rate for the stitched stream.

19. The method of claim 15 , further comprising display the stitched stream on a monitor within a single frame.

20. The method of claim 15 , further comprising automatically, by the processing unit, increasing a size of a video image associated with one of the plurality of field-of-views based on a video analytic algorithm.
