FOV in model view & distance to object (2.nd time)
« on: September 08, 2023, 02:31:38 PM »
Hello to everyone !

Hope you're doing well!

Can someone, please, explain how  the perspective "FOV" in the model view is calculated?
I'm trying to suggest the distance from a scanned object in a photograph...

For example:
if you have a face scan...
FOV 70: you can see the ears from the front
FOV 30 to 0 : you can't see them

It's the same then stepping back and forth - changing the distance to the object. Hopefully you can help me out!

THANK YOU VERY MUCH!

Hello jkova96,

FOV=Field of view, tell you how much scene you can view (in degree) from the rendering camera position.

If you import the Metashape model in a 3D editing software (ex. Blender) you can adjust the FOV and many other parameters related to the camera. For example you can simulate a camera that's 10 meters away, using a specific focal lenght, etc..

Hi tazzo,
Well I know it's about Field of View, but field of view can be measured horizontally, vertically and diagonally isn't it?
I just want to know which field of view is it represented by numbers (horizontal, vertical, diagonal)?
I can tell you that - from my observations that should be Field of View measured vertically.
Well, if you agree with me - then let me know about that.
Thanks :)
Have a nice day :)
