[Vision] Calculate Horizontal and Vertical FOV from Diagonal FOV and Aspect Ratio

Refferd from 

Estimate visible bounds of webcam using diagonal fov

Converting diagonal field of view and aspect ratio to horizontal and vertical field of view

Logitech BRIO Ultra HD Pro Webcam

 

I gotta calculate H, V FOV from Diagonal FOV. and I got Information about diagonal fov and aspect ratio only. so I've calculated it reffed vrguy blog.

 

1. Given Information (Logitech BRIO Ultra HD Pro Webcam)

Diagonal: 78°

Diagonal: 65°

 

Diagonal: 90°

Horizontal: 82.1°

Vertical: 52.2°

2. Check Aspect Ratio

when I check the table from vrguy blog, It is 90 degree when Horizontal fov is 82.1° Vertical fov is 52.2°, and the Aspect ratio is 16:9(1.78:1).

3. when It's 78 degree or 65 degree?

I made a Excel file to calculate about other Diagonal FOV.

so if you need it, just use it.

 

Thanks for vrguy again.
