• [2024/7/05] Check out our Metric3D v2, a sota depth and normal model in terms of accuracy.
• [2024/7/02] Paper accepted to ECCV'24.
• [2024/4/16] Release GeoWizard V2, a version with more robust and three-dimensional normal.
• [2024/3/25] Thanks to Kijai for incorporating GeoWizard into ComfyUI Version.
• [2024/3/19] Release paper, project page, and code.

We test our codes under the following environment: Ubuntu 22.04, Python 3.9.18, CUDA 11.8.

1. Clone this repository.

git clone [email protected]:fuxiao0719/GeoWizard.git
cd GeoWizard

2. Install packages

conda create -n geowizard python=3.9
conda activate geowizard
pip install -r requirements.txt
cd geowizard

Place your images in a directory input/example (for example, where we have prepared several cases), and run the following inference. The depth and normal outputs will be stored in output/example.

python run_infer.py \
    --input_dir ${input path} \
    --output_dir ${output path} \
    --ensemble_size ${ensemble size} \
    --denoise_steps ${denoising steps} \
    --seed ${seed} \
    --domain ${data type}
# e.g.
python run_infer.py \
    --input_dir input/example \
    --output_dir output \
    --ensemble_size 3 \
    --denoise_steps 10 \
    --seed 0 \
    --domain "indoor"

Inference settings: --domain: Data type. Options: "indoor", "outdoor", and "object". Note that "object" is best for background-free objects, like that in objaverse. We find that "indoor" will suit in most scenarios. Default: "indoor". --ensemble_size and --denoise_steps: trade-off arguments for speed and performance, more ensembles and denoising steps to get higher accuracy. Default: 3 and 10 (For academic comparison, please set 10 and 50, respectively).

We additionally train a v2-model with some architecture modifications (replace image CLIP with three types of text embeddings). Now it can generate more realistic and three-dimensional normal maps on some rare images (e.g., cartoon style, see below).

python run_infer_v2.py \
    --input_dir ${input path} \
    --output_dir ${output path} \
    --ensemble_size ${ensemble size} \
    --denoise_steps ${denoising steps} \
    --seed ${seed} \
    --domain "indoor"
# e.g.
python run_infer_v2.py \
    --input_dir input/example \
    --output_dir output \
    --ensemble_size 3 \
    --denoise_steps 10 \
    --seed 0 \
    --domain "indoor"

python run_infer_v2.py \
    --input_dir input/example_object \
    --output_dir output_object \
    --ensemble_size 3 \
    --denoise_steps 10 \
    --seed 0 \
    --domain "object"

First put the generated depth & normal npy files under the folder bini/data along with the segmented foreground mask (mask.png. If not set, it will utilize the whole image as mask). We provide two examples for the data structure. Then run the command as follow.

cd ../bini

python bilateral_normal_integration_numpy.py \
    --path ${input path} \
    -k ${k} \
    --iter ${iterations} \
    --tol ${tol}

# e.g. (paper setting)
python bilateral_normal_integration_numpy.py --path data/test_1 -k 2 --iter 50 --tol 1e-5

Here we provide two training scripts train_depth_normal.py and train_depth_normal_v2.py. You need to modify the configs accordingly. We use 8GPUs for training as default, and you can switch 8gpu.yaml to 1gpu.yaml with fewer computing resources. We provide our dataloader format in dataloader/mix_loader.py and encourage you to train it on your own customized datasets.

cd training/scripts

# v1 model
sh train_depth_normal.sh

# v2 model
sh train_depth_normal_v2.sh
