I2-SDF: Intrinsic Indoor Scene Reconstruction and Editing via Raytracing in Neural SDFs (CVPR 2023)

Project Page | Paper | Dataset

Setup

Installation

conda env create -f environment.yml
conda activate i2sdf

Data preparation

Download our synthetic dataset and extract them into data/synthetic. If you want to run on your customized dataset, we provide a brief introduction to our data convention here.

Dataset

We provide a high-quality synthetic indoor scene multi-view dataset, with ground truth camera pose and geometry annotations. See HERE for data conventions. Click HERE to download.

3D Reconstruction and Novel View Synthesis

Training

python main_recon.py --conf config/<config_file>.yml --scan_id <scan_id> -d <gpu_id> -v <version>

Note: config/synthetic.yml doesn't contain light mask network, while config/synthetic_light_mask.yml contains.

If you run out of GPU memory, try to reduce the split_n_pixels (i.e. validation batch size), batch_size in the config. The default parameters are evaluated under RTX A6000 (48GB). For RTX 3090 (24GB), try to set split_n_pixels 5000.

Evaluation

Novel view synthesis

python main_recon.py --conf config/<config_file>.yml --scan_id <scan_id> -d <gpu_id> -v <version> --test [--is_val] [--full]

The optional flag --is_val evaluates on the validation set instead of training set, --full produces full-resolution rendered images without downsampling.

View Interpolation

python main_recon.py --conf config/<config_file>.yml --scan_id <scan_id> -d <gpu_id> -v <version> --test --test_mode interpolate --inter_id <view_id_0> <view_id_1> [--full]

Generates a view interpolation video between 2 views. Requires ffmpeg being installed.

The number of frames and frame rate of the video can be specified by options.

Mesh Extraction

python main_recon.py --conf config/<config_file>.yml --scan_id <scan_id> -d <gpu_id> -v <version> --test --test_mode mesh

Intrinsic Decomposition and Scene Editing

Brewing🍺, code coming soon.
