About data preprocessing

[Lz-gzhu]

Hi,
I'm trying to figure out the data preprocessing code (Kitti_loader.py ) , maybe the description of the data preprocessing in the README is lacking some kind of details. For instances, "This will create a new dataset in $dest. You can find the required preprocessing in:"

Maybe I'm not good enough regarding code comprehension , haha

Looking forward to ur reply @wvangansbeke
