during training

Hello everyone,
I have a question regarding Reality Capture. When computing a model in RC, are any cache files generated? I need to know how the images’ weights on the model’s point cloud are represented during training. I noticed that RC stores some cache files in the temp folder—what is the purpose of these files? Can I read them, and if so, how?

Additionally, I observed that there are some files in the project save folder. Are the model files in these directories generated during training? What do these files represent, and can I make use of them?

Finally, I would like to export the model in COLMAP format. I noticed that the exported camera model is in SIMPLE_RADIAL, but I need a pinhole camera model export format. How should I adjust the settings to achieve this?

Thank you for your help!

Hello @biabiabia66
To answer your questions:

Yes, there are cache files generated:

Which weight setting do you mean?
The cache files are not readable, they are there for the smooth operation of the project, also detected features can be stored there.

Regarding project folder you can find more info here.
They are created for the project, not for your usage.

To get PINHOLE cameras you need to use the undistorted images and set the camera’s Prior lens distortion as Prior: Fixed, Camera model: No lens distortion for the selected images after import (see Camera Models — COLMAP 3.12.0.dev0 documentation).
