PointNet && PointNet++

This is the repository of PointNet and PointNet++. The original code is implemented by Tensorflow, while we provide PyTorch version of PointNet and PointNet++ in this project.

Note: we only give the illustration of PyTorch version, and please find the original TF code in ./TF.

Environment

Python 3.6

PyTorch 1.2.0

CUDA 10.2

Dataset

You can downlown the data from here, and then unzip it and rename as ./data.

Training

For pointnet,

cd ./pointnet
python  train_segmentation.py --mode train 

For pointnet++,

cd ./pointnet2
python setup.py install
python  train_segmentation2.py --mode train 

Test

For pointnet,

bash test.sh  

For pointnet++,

bash test.sh

You also can choose different categories to evaluate performance under IOU
