Preprocess script for the official DTU dataset

[mwang625]

Hi authors, thanks for the inspiring and awesome work!

One question about the DTU dataset, where can I find the codes to process the raw official DTU dataset( https://roboimagedata.compute.dtu.dk/?page_id=36) to the one you provided (https://www.dropbox.com/s/s6psnh1q91m4kgo/DTU.zip)? I'm curious about which set of images (cleaned or rectified) and what lightning did you use. Sorry if I missed the code somewhere in the repo, thanks in advance for your help!
