Depth Anything 3: DA3-SMALL

# noqa: E501

Model Description

DA3 Small model for multi-view depth estimation and camera pose estimation. Efficient foundation model with unified depth-ray representation.

| Property | Value | |----------|-------| | Model Series | Any-view Model | | Parameters | 0.08B | | License | Apache 2.0 |

Capabilities

• ✅ Relative Depth
• ✅ Pose Estimation
• ✅ Pose Conditioning

Quick Start

Installation

git clone https://github.com/ByteDance-Seed/depth-anything-3
cd depth-anything-3
pip install -e .

Basic Example

import torch
from depth_anything_3.api import DepthAnything3

# Load model from Hugging Face Hub
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model = DepthAnything3.from_pretrained("depth-anything/da3-small")
model = model.to(device=device)

# Run inference on images
images = ["image1.jpg", "image2.jpg"]  # List of image paths, PIL Images, or numpy arrays
prediction = model.inference(
    images,
    export_dir="output",
    export_format="glb"  # Options: glb, npz, ply, mini_npz, gs_ply, gs_video
)

# Access results
print(prediction.depth.shape)        # Depth maps: [N, H, W] float32
print(prediction.conf.shape)         # Confidence maps: [N, H, W] float32
print(prediction.extrinsics.shape)   # Camera poses (w2c): [N, 3, 4] float32
print(prediction.intrinsics.shape)   # Camera intrinsics: [N, 3, 3] float32

Command Line Interface

# Process images with auto mode
da3 auto path/to/images \
    --export-format g
