Get poses from ARkit data

[Vadkoz]

Hi, All works fine via LLFF(COLMAP), but I have extrinsic data (quaternions and translation) from ARkit. But if simply pass my own quaternions and translation vector instead COLMAPs into img2poses script from LLFF, the result is clearly wrong. How do I need to preprocess ARkit data to make it similar to COLMAP before passing it to the img2poses script? Or what transformation do I need to do to deal with ARkit data? Or how to translate ARkit data to blender format? I use ios_logger from this repo to get ARkit data. Thanks!

I'm using the 3D Scanner App to obtain the pose data.
