Introduction

This is the official inplementation of Recurrent Slice Networks for 3D Segmentation on Point Clouds (RSNet), which is going to appear in CVPR 2018.

RSNet is a powerful and conceptually simple network for 3D point cloud segmentation tasks. It is fast and memory-efficient. In this repository, we release codes for training a RSNet on the S3DIS segmentation dataset. Training on other datasets can be easily achieved by following the same process.

Dependencies

• python (tested on python2.7)
• PyTorch (tested on 0.3.0)
• cffi
• h5py

Installation

1. Clone this repository.
2. Compile source codes for slice pooling/unpooling layers by following the readme file in layers

Data Preparation

1. Process the S3DIS dataset by following the readme file in data.

Train

1. Launch training by the command below:

$ python train.py

Type python train.py --help for detailed input options. Be default, it will start the training by using Area 5 as testing set and others as training set.

During training, visualizations (.obj files) of intermediate predictions will be dumped into the folder results after each epoch. And they will be evaluated and saved in test_log.txt.
