RPM-Net: Recurrent Prediction of Motion and Parts from Point Cloud

Introduction

We introduce RPM-Net, a deep learning-based approach which simultaneously infers movable parts and hallucinates their motions from a single, un-segmented, and possibly partial, 3D point cloud shape. RPM-Net is a novel Recurrent Neural Network (RNN), composed of an encoder-decoder pair with interleaved Long Short-Term Memory (LSTM) components, which together predict a temporal sequence ofpointwise displacements for the input point cloud. At the same time, the displacements allow the network to learn movable parts, resulting in a motion-based shape segmentation.

For more details, please refer to our project page.

Usage

All codes are tested under Tensorflow 1.13.1 GPU version and Python 3.6 on Ubuntu 14.04.

First, please download RPM-Net_data.zip, and extract to RPM-Net/data/ folder.

Run train.py to train RPM-Net, the model will be saved in RPM-Net/output/ folder.

Before testing, please modify the model_path and eval_dir in test.py, the predicted pointcloud and segmentation files will be saved in RPM-Net/output/YOUR_MODEL_PATH/eval/ folder.
