FusionAwareConv

This project is based on our CVPR 2020 paper,Fusion-Aware Point Convolution for Online Semantic 3D Scene Segmentation <img src="asset/scene0708_00.gif" height=250px align="right"/>

Introduction

We propose a novel fusionaware 3D point convolution which operates directly on the geometric surface being reconstructed and exploits effectively the inter-frame correlation for high quality 3D feature learning.

Installation

This code is based on PyTorch and needs open3D for convenient visualization

Our code has been tested with Python 3.7.6, PyTorch 1.1.0, open3d 0.9.0, CUDA 10.0 on Ubuntu 16.04.

Dataset and Pre-trained weights

We use the ScanNetv2 as our test dataset. If you want to test all the data, you can download the ScanNetV2 dataset from here. For a quick visulazation test, we provide several pre-proessing scenes of the test set sequence. Put the scene.h5 in path/data.

We also provide the pre-trained weights for ScanNet benchmark, you can download from here. After finishing the download, put the weights in path/weight.

Test

Online Segmentation Visulization

We have already intergrate the open3d for visulizaiton, you can run the command below:

python vis_sequence.py --weight2d_path=weight_path/weight2d_name --weight3d_path=weight_path/weight3d_name --gpu=0 --use_vis=1 --scene_path=scene_path/scene_name

The complete segmentation result will be generated in result.ply.

Global-local Tree Visualization

We achieve the a test demo for global-local tree visulizaiton only. Run the command below to see the processing of the tree built.

python vis_sequence.py  --use_vis=1 --scene_path=scene_path/scene_name

The complete result will be generated in result_GLtree.ply.
