Colmap convert camera model simple radial output to pinhole output.

[Gurutva]

Is your feature request related to a problem? Please describe.

When I use real llff colmap output already given with dataset to run gaussian splatting, it gives me error because the output of the camera model is a simple radial camera and gaussian splatting needs pinhole camera model,my question is:

Is there a way to convert simple radial to pinhole camera model?

You can use the image_undistorter to create undistorted versions of the images (removing radial and other distortions such that the resulting images can be described by a pinhole model). It also writes out a sparse 3D model containing pinhole camera parameters for the undistorted images.
