Plane-DUSt3R: Unposed Sparse Views Room Layout Reconstruction in the Age of Pretrain Model

This model, presented in the paper Unposed Sparse Views Room Layout Reconstruction in the Age of Pretrain Model, performs multi-view room layout reconstruction from unposed sparse views. It leverages the DUSt3R framework and is fine-tuned on the Structure3D dataset to estimate structural planes, offering a streamlined, end-to-end solution.

This repository contains the official implementation of the paper "Unposed Sparse Views Room Layout Reconstruction in the Age of Pretrain Model". Accepted by ICLR 2025. [arXiv]

Overview

Plane-DUSt3R is a novel pipeline for multi-view room layout reconstruction from unposed sparse views.

It combines single-view plane detection with multi-view 3D reconstruction method to achieve robust and accurate plane detection in indoor scenes.

Get Started

Installation

Create the environment, here we show an example using conda.

conda activate planedust3r 
conda install pytorch==2.2.0 torchvision==0.17.0 torchaudio==2.2.0 pytorch-cuda=11.8 -c pytorch -c nvidia  # use the correct version of cuda for your system. test pass on pytorch 2.2.0
cd MASt3R
pip install -r requirements.txt
pip install -r dust3r/requirements.txt

Optional, compile the cuda kernels for RoPE (as in CroCo v2).

# DUST3R relies on RoPE positional embeddings for which you can compile some cuda kernels for faster runtime.
cd dust3r/croco/models/curope/
python setup.py build_ext --inplace
cd ../../../../

cd ..
pip install -r requirements.txt

Checkpoints

mkdir -p checkpoints/

And download the plane-dust3r checkpoint from the following google drive link: plane-dust3r

The plane-dust3r checkpoint is also available on huggingface huggingface

And download the noncuboid checkpoints from the following google drive link: noncuboid

Usage

Interactive Demo

python3 MASt3R/dust3r/demo.py --weights checkpoints/checkpoint-best-onlyencoder.pth
# Use --weights to load a checkpoint from a local file

Training

please see branch train

Evaluation

Data preparation

Please download Structured3D dataset from here.

The directory should be like this:

root_path
└── scene_id_1
│   └── 2D_rendering
│       └── room_id_1
│           └── perspective
│               └── full
│                   ├── position_id_1
│                   │   └── rgb_rawlight.png
│                   ├── position_id_2
│                   │   └── rgb_rawlight.png
│                   └── ...
└── scene_id_2
    └── 2D_rendering
        └── room_id_2
            └── perspective
                └── full
                    ├── position_id_1
                    │   └── rgb_rawlight.png
                    ├── position_id_2
                    │   └── rgb_rawlight.png
                    └── ...

Since we use the plane depth to evaluate the performance, we need to convert the plane layout to plane depth map.

python convert_plane_depth.py --path /path/to/Structured3D/dataset

To evaluate on test set, run:

python evaluate_planedust3r.py \
    --dust3r_model checkpoints/checkpoint-best-onlyencoder.pth \
    --noncuboid_model checkpoints/Structured3D_pretrained.pt \
    --root_path /path/to/Structured3D/dataset \
    --save_path /path/to/save/result \
    --device cuda

The evaluation will create a folder in $save_path$ in the root directory, and save the results in $save_path$/scene_number/room_id/. If you dont want to save the results, you can set --save_flag False
