Habitat-Matterport 3D Dataset (HM3D)

The Habitat-Matterport 3D Research Dataset is the largest-ever dataset of 3D indoor spaces. It consists of 1,000 high-resolution 3D scans (or digital twins) of building-scale residential, commercial, and civic spaces generated from real-world environments.

HM3D is free and available here for academic, non-commercial research. Researchers can use it with FAIR’s Habitat simulator to train embodied agents, such as home robots and AI assistants, at scale.

example

This repository contains the code and instructions to reproduce experiments from our NeurIPS 2021 paper. If you use the HM3D dataset or the experimental code in your research, please cite the HM3D paper.

Installation instructions

We provide a common set of instructions to setup the environment to run all our experiments.

Clone the HM3D github repository and add it to PYTHONPATH.

git clone https://github.com/facebookresearch/habitat-matterport3d-dataset.git
cd habitat-matterport3d-dataset
export PYTHONPATH=$PYTHONPATH:$PWD

Create conda environment and activate it.

conda create -n hm3d python=3.8.3
conda activate hm3d

Install habitat-sim using conda.
```
conda install habitat-sim headless -c conda-forge -c aihabitat
```
See habitat-sim's installation instructions for more details.
Install trimesh with soft dependencies.
```
pip install "trimesh[easy]==3.9.1"
```
Install remaining requirements from pip.
```
pip install -r requirements.txt
```

Downloading datasets

In our paper, we benchmarked HM3D against prior indoor scene datasets such as Gibson, MP3D, RoboThor, Replica, and ScanNet.

Download each dataset based on these instructions from habitat-sim. In the case of RoboThor, convert the raw scan assets to GLB using assimp.
```
assimp export <SOURCE SCAN FILE> <GLB FILE PATH>
```

Once the datasets are download and processed, create environment variables pointing to the corresponding scene paths.

export GIBSON_ROOT=<PATH TO GIBSON glbs>
export MP3D_ROOT=<PATH TO MP3D glbs>
export ROBOTHOR_ROOT=<PATH TO ROBOTHOR glbs>
export HM3D_ROOT=<PATH TO HM3D glbs>
export REPLICA_ROOT=<PATH TO REPLICA plys>
export SCANNET_ROOT=<PATH TO SCANNET glbs>

Running experiments

We provide the code for reproducing the results from our paper in different directories.

scale_comparison contains the code for comparing the scale of HM3D with other datasets (Tab. 1 in the paper).
quality_comparison contains the code for comparing the reconstruction completeness and visual fidelity of HM3D with other datasets (Fig. 4 and Tab. 5 in the paper).
pointnav_comparison contains the configs and instructions to train and evaluate PointNav agents on HM3D and other datasets (Tab. 2 and Fig. 7 in the paper).

We further provide README files within each directory with instructions for running the corresponding experiments.
