Dual camera regions of interest display
View Patent ↗A method of determining a region of interest may include with a first image capturing device, determining a region of interest within a field of view common between the first image capturing device and a second image capturing device, the first image capturing device capturing an image at a lower resolution than the second image capturing device; determining a corner defining the region of interest; and upscaling the determined corner to match a corner within a field of view of an image captured by the second image capturing device.
1. A method of determining a region of interest, comprising:
with a first image capturing device, determining a region of interest within a field of view of the first image capturing device and a second image capturing device, the first image capturing device capturing an image at a lower resolution than the second image capturing device, the field of view being the same in the first image capturing device and the second image capturing device;
determining a corner defining the region of interest; and
upscaling a resolution of the determined corner to match a resolution of a corner within a field of view of an image captured by the second image capturing device which has a higher resolution than the first image capturing device.
2. The method of claim 1 , comprising completing the upscaling of the corner within a single frame.
3. The method of claim 1 , wherein the first image capturing device and second image capturing device are within the same device.
4. The method of claim 1 , wherein the first image capturing device and second image capturing device have different fields of view.
5. The method of claim 1 , wherein the first image capturing device is an image capturing device that captures an image within the electromagnetic spectrum.
6. The method of claim 1 , wherein a frame rate of the first image capturing device is equal to or higher than a frame rate of the second image capturing device.
7. The method of claim 1 , wherein the first image capturing device sends image data captured to a host device for corner determination and corner upscaling.
8. The method of claim 1 , further comprising performing a keystone correction to register the determined corners to a perspective of the second image capturing device.
9. The method of claim 1 , wherein determining a region of interest comprises performing pixel analysis to identify an object to be tracked within the region of interest.
10. The method of claim 1 , wherein determining a region of interest comprises performing object recognition to identify an object to be tracked within the region of interest.
11. The method of claim 1 , wherein upscaling the determined corner comprises increasing a sampling rate of portions of frames where the determined corners are located within frames recorded by the first image capturing device.
12. The method of claim 1 , further comprising upscaling just the determined corner to match the corner within the field of view of the image captured by the second image capturing device.
13. An image capturing system, comprising:
a first camera, comprising:
a region of interest module to:
identify a region of interest, wherein the region of interest comprises an object within a field of view that is to be tracked; and
determine a corner defining the region of interest;
a second camera having a higher resolution than the first camera; and
an image upscaling module to upscale a resolution of a determined corner to match a resolution of the corners within a field of view within an image captured by the second camera while other portions of the region of interest are not upscaled.
14. The image capturing system of claim 13 , wherein the image upscaling module receives upscaling data from a processor of a host device communicatively coupled to the image capturing system.
15. The image capturing system of claim 13 , wherein the first camera records an infrared image.
16. The image capturing system of claim 14 , wherein the host device streams a video image of the matched corners within the field of view of the captured images received by the second camera.
17. The image capturing system of claim 13 , wherein a frame rate of the first camera is equal to or higher than a frame rate of the second camera.
18. A camera device, comprising:
a first image capturing device to:
capture a low-resolution image including a region of interest, wherein the region of interest comprises an object within a field of view that is to be tracked;
track the object with low-resolution image data; and
update the region of interest as the object moves;
a second image capturing device to capture a high-resolution image including the region of interest;
a region of interest module to demarcate the corners bounding the region of interest; and
an image signal processor to:
upscale a resolution of the demarcated corners to match a resolution of a corner within a field of view of an image captured by the second image capturing device which has a higher resolution than the first image capturing device;
receive an upscaled image from the first image capturing device that includes the demarcated corners defining the region of interest in the high-resolution image;
identify coordinates defining the demarcated corners within the high-resolution image of the second image capturing device; identify a region of interest within the field of view of the second image capturing device based on an identification of coordinates of the demarcated corners.
19. The camera device of claim 18 , wherein a frame rate of the first image capturing device is equal to or higher than a frame rate of the second image capturing device.
20. The camera device of claim 18 , wherein the first image capturing device is an infrared camera.
