Cameras lens distortion extension not visible

[yhofmann]

Hi,
I came across the following documentation while looking for more information on simulating real world cameras: Cameras — Omniverse Materials and Rendering.
However I could not find the extension and can also not add this to my camera. How can I access the features, especially the OpenCV pinhole camera since from my experience do the distortion parameters for a normal pinhole camera (or any other fisheye except polynomial) not have an effect, e.g changing s does not enable me to simulate radial distortion.

Thanks

Hi @yhofmann! Are you looking for extension omni.usd.schema.omni_lens_distortion? Which Isaac Sim version are you using? I am able to find this extension in Isaac Sim 4.5.

Hi @zhengwang ,
Okey, another reason to push the migration from 2023.1.1 to 4.5 as quickly as possible.

Thanks for checking it

Hi @zhengwang,
I was now able to find the extension in a 4.5 test scene

However, it requires the omni.kit.widget.schema_api extension, which I cannot find:

How to load/find this extension?

[zhengwang]

omni.kit.widget.schema_api extension is available in Isaac Sim 5.0, which is our latest release.
omni.usd.schema.omni_lens_distortion is also available in Isaac Sim 5.0.
