Hi, It seemed that your preprocess script for panorama and fisheye cameras are missing. How can I preprocess panorama datasets and fisheye datasets?

[LetianHuang]

Hello, we're thrilled that you find our work interesting. To process other datasets, you can write custom scripts tailored to your requirements. Our main focus is on conducting a detailed error analysis of Gaussian projections and providing a differentiable rendering algorithm with minimal projection error that supports various camera models. : )

As for training with panoramic images, you can refer to our other work on reconstructing indoor scenes from panoramic images for guidance on processing the Matterport dataset. The dataset reader implementation is available here: https://github.com/LeoDarcy/360GS/blob/LetianHuang-layout-reg/scene/dataset_readers.py. However, this work is not fully open-sourced yet. We plan to gradually release additional components in the future. : )

It appeared that the FOVX, FOVY was using a fixed numbers (FovY = focal2fov(w * 0.2, h)
FovX = focal2fov(w * 0.2, w) )?
Is there any mathematical equations for explaining this?
From my knowledge, the intrinsics does not matter in panorama images. So I simply set FOVX = 2* pi ; FOVY= pi, is that right for pano images? My images are 1024 * 512 using equirectangular projection.

I suggest you carefully review the supplementary materials of the paper and the diff-gaussian-rasterization-panorama source code in the repository. The FoV parameter does not affect the results of panoramic images.
In addition, the source code you mentioned includes the comment # Use any number instead of Fov, indicating that any value can be used.
