This repository contains the source code for the paper Learning Geometric Transformation for Point Cloud Completion

Installation

Moreover, this repository introduces an integrated Point Cloud Completion Benchmark implemented in Python 3.8, PyTorch 1.8 and CUDA 11.4.

1. Install dependencies:

• h5py 3.9.0
• opencv-python 4.7.0
• matplotlib 3.7.1
• transforms3d 0.4.1
• munch 3.0.0
• open3d 0.13.0
• PyTorch 1.8.0
• PyYAML 5.4.1

2. Compile PyTorch 3rd-party modules (ChamferDistancePytorch, emd, expansion_penalty, MDS, Pointnet2.PyTorch)

MVP Dataset

Please download the MVP Dataset (Dropbox or Google Drive) to the folder data.

Usage

• To train a model: run python train.py -c *.yaml, e.g. python train.py -c pcn.yaml
• To test a model: run python test.py -c *.yaml, e.g. python test.py -c pcn.yaml
• Config for each algorithm can be found in cfgs/.
• run_train.sh and run_test.sh are provided for SLURM users.
