ply to hdf5 #16

Hey how do you convert the .ply files in original dataset(3DV 2016 (original instance annotation of 100+ scenes)) to hdf5(CVPR 2018 (evaluating semantic segmentation with NYU-D v2 40 classes))

songuke commented 5 years ago

Hi, we had an in-house C++ library tied to Python so that we can iterate and parse the scenes from PLY, downsample the points, divide them into blocks, and store the results to HDF5. We did some additional checks and discarded point clouds that are empty or having too few points in the block.

Any script for that conversion? I want to create some of my own data files, annotate and add to training data. i.e I want to convert ply files(point clouds) and xml files(annotations) to hdf5 .

Please email me at binhson.hua at gmail. I will send the script to you.
