RGBCam/RCam/LCam overlap

Hi all,
How can I know how the RGBCamera overlap the left and right camera?
Is it something like this?


I believe the right and left cameras have a MUCH bigger fov and aspect ratio than the RPG camera.

What are you trying to achieve??

Thanks for your answer, the problem is the one I posted here:


A short recap: when the user position a box in the UI, I have to grab a screenshot of the image under the box, to obtain a cropped image of the entire view.
I can do it in the emulator, but with the glasses the camera I use to grab the image doesn’t contain the real world, so when I crop i get an empty box.
