MoGe is a powerful model for recovering 3D geometry from monocular open-domain images. The model consists of a ViT encoder and a convolutional decoder. It directly predicts an affine-invariant point map as well as a mask that excludes regions with undefined geometry (e.g., sky), from which the camera shift, camera focal length and depth map can be further derived.

🌟Updated on 2024/11/28 - CHANGELOG:

• Supported user-provided camera FOV.
• Added the script for panorama images scripts/infer_panorama.py.

• Clone this repository.

  git clone https://github.com/microsoft/MoGe.git
  cd MoGe

• Python (>= 3.10) environment:

  • torch (>= 2.0) and torchvision (compatible with the torch version).

    MoGe should be compatible with most requirements versions. Please check the requirements.txt for more details if you have concerns.

The ViT-Large model has been uploaded to Hugging Face hub at Ruicheng/moge-vitl. You may load the model via MoGeModel.from_pretrained("Ruicheng/moge-vitl") without manually downloading.

If loading the model from a local file is preferred, you may manually download the model from the huggingface hub and load it via MoGeModel.from_pretrained("PATH_TO_LOCAL_MODEL.pt").

Here is a minimal example for loading the model and inferring on a single image.

import cv2
import torch
from moge.model import MoGeModel

device = torch.device("cuda")

# Load the model from huggingface hub (or load from local).
model = MoGeModel.from_pretrained("Ruicheng/moge-vitl").to(device)                             

# Read the input image and convert to tensor (3, H, W) and normalize to [0, 1]
input_image = cv2.cvtColor(cv2.imread("PATH_TO_IMAGE.jpg"), cv2.COLOR_BGR2RGB)                       
input_image = torch.tensor(input_image / 255, dtype=torch.float32, device=device).permute(2, 0, 1)    

# Infer 
output = model.infer(input_image)
# `output` has keys "points", "depth", "mask" and "intrinsics",
# The maps are in the same size as the input image. 
# {
#     "points": (H, W, 3),    # scale-invariant point map in OpenCV camera coordinate system (x right, y down, z forward)
#     "depth": (H, W),        # scale-invariant depth map
#     "mask": (H, W),         # a binary mask for valid pixels. 
#     "intrinsics": (3, 3),   # normalized camera intrinsics
# }
# For more usage details, see the `MoGeModel.infer` docstring.

Make sure that gradio is installed and then run the following command to start the web demo:

python scripts/app.py   # --share for Gradio public sharing

The web demo is also available at our Hugging Face space.

Run the script scripts/infer.py via the following command:

# Save the output [maps], [glb] and [ply] files
python scripts/infer.py --input IMAGES_FOLDER_OR_IMAGE_PATH --output OUTPUT_FOLDER --maps --glb --ply

# Show the result in a window (requires pyglet < 2.0, e.g. pip install pyglet==1.5.29)
python scripts/infer.py --input IMAGES_FOLDER_OR_IMAGE_PATH --output OUTPUT_FOLDER --show

For detailed options, run python scripts/infer.py --help:

Usage: infer.py [OPTIONS]

  Inference script for the MoGe model.

Options:
  --input PATH                Input image or folder path. "jpg" and "png" are
                              supported.
  --fov_x FLOAT               If camera parameters are known, set the
                              horizontal field of view in degrees. Otherwise,
                              MoGe will estimate it.
  --output PATH               Output folder path
  --pretrained TEXT           Pretrained model name or path. Default is
                              "Ruicheng/moge-vitl"
  --device TEXT               Device name (e.g. "cuda", "cuda:0", "cpu").
                              Default is "cuda"
  --resize INTEGER            Resize the image(s) & output maps to a specific
                              size. Default is None (no resizing).
  --resolution_level INTEGER  An integer [0-9] for the resolution level of
                              inference. The higher, the better but slower.
                              Default is 9. Note that it is irrelevant to the
                              output resolution.
  --threshold FLOAT           Threshold for removing edges. Default is 0.03.
                              Smaller value removes more edges. "inf" means no
                              thresholding.
  --maps                      Whether to save the output maps and fov(image,
                              depth, mask, points, fov).
  --glb                       Whether to save the output as a.glb file. The
                              color will be saved as a texture.
  --ply                       Whether to save the output as a.ply file. The
                              color will be saved as vertex colors.
  --show                      Whether show the output in a window. Note that
                              this requires pyglet<2 installed as required by
                              trimesh.
  --help                      Show this message and exit.

NOTE: This is an experimental extension of MoGe.

The script will split the 360-degree panorama image into multiple perspective views and infer on each view separately. The output maps will be combined to produce a panorama depth map and point map.

Note that the panorama image must have spherical parameterization (e.g., environment maps or equirectangular images). Other formats must be converted to spherical format before using this script. Run python scripts/infer_panorama.py --help for detailed options.
