colmap camera model not handled #14

StevenssW commented 2 months ago

I shot a video using the ordinary lens of an iPhone. The data has no distortion, but when I train, it prompts me that a distorted camera model was used. How can I solve this? Thank you. 2024-04-29_16-56

Hi, colmap model should work out of box, how do you preprocess your data?

mizeller commented 1 month ago

The same thing just happened to me. I also just captured a short video w/ my phone. After processing the data, my camera model is 'SIMPLE_RADIAL'. I'm using the following COLMAP version:

COLMAP 3.10-dev -- Structure-from-Motion and Multi-View Stereo
(Commit 06a80538 on 2024-03-21 with CUDA)

Did you find a solution for this problem?

Hi, I think you need to undistort your colmap model. Please check here https://github.com/graphdeco-inria/gaussian-splatting?tab=readme-ov-file#processing-your-own-scenes
