How to get the camera intrinsic parameters from the original YouTube wild videos?

[luckymingjia]

I watch that in the dataset, you have supplied the camera intrinsics, but I do not know how do you get them when you create the dataset from the original YouTube ? So could you please explain it for me or tell me what method you have adopted to solve this ? Thank you very much!

Hi, the camera intrinsics are estimated by COLMAP structure-from-motion. We give a bit of explanation if the paper and supplemental material but experimenting with COLMAP is probably required if you haven't used it before.
