How to modify the camera's field of view

Omniverse Isaac Sim
1

Hello,
I am now using Isaac Docker with version 2023.1.1. I added a camera in isaac, please how can I modify the field of view of the camera, I don’t find the option to modify the FOV in the property page of the camera. Thanks for your reply.

@liuqiran1997 i believe the Focal Length param is what controls the overall FOV. below is one of many ways you could change the value:

import omni

stage = omni.usd.get_context().get_stage()
prim = stage.GetPrimAtPath("/World/Camera")

prim.GetAttribute('focalLength').Set(50.0)

@Simplychenable , am i understanding correctly that I cannot set the the vertical field of view only in a camera in omniverse??

@danielle.sisserman technically you can, but based on one of the mod’s response in this thread and the gif i posted, it doesn’t seem like it’s a param that makes much sense to modify:

do you find yourself needing to change this specific setting?

@Simplychenable Yes, I need to change both the horizontal and vertical fov. Its makes sense that the vertical aperture is set from the result of the image aspect ratio and the horizontal aperture. I will try that. Thank you

Hi there,

the vertical aperture is automatically computed when setting the horizontal one, this is because non-square pixels are currently not supported:

import omni

stage = omni.usd.get_context().get_stage()
prim = stage.GetPrimAtPath("/World/Camera")

prim.GetAttribute('horizontalAperture').Set(36.0)
# Square pixel (fy = fx) so vertical aperture is computed from horizontal aperture
# prim.GetAttribute('verticalAperture').Set(36.0)

Best,
Andrei
