This work presents **Depth Anything 3 (DA3)**, a model that predicts spatially consistent geometry from
arbitrary visual inputs, with or without known camera poses.
In pursuit of minimal modeling, DA3 yields two key insights:
- 💎 A **single plain transformer** (e.g., vanilla DINO encoder) is sufficient as a backbone without architectural specialization,
- ✨ A singular **depth-ray representation** obviates the need for complex multi-task learning.

🏆 DA3 significantly outperforms
[DA2](https://github.com/DepthAnything/Depth-Anything-V2) for monocular depth estimation,
and [VGGT](https://github.com/facebookresearch/vggt) for multi-view depth estimation and pose estimation.
All models are trained exclusively on **public academic datasets**.

## 📰 News
- **30-11-2025:** Add [`use_ray_pose`](#use-ray-pose) and [`ref_view_strategy`](docs/funcs/ref_view_strategy.md) (reference view selection for multi-view inputs).   
- **25-11-2025:** Add [Awesome DA3 Projects](#-awesome-da3-projects), a community-driven section featuring DA3-based applications.
- **14-11-2025:** Paper, project page, code and models are all released.

## ✨ Highlights

### 🏆 Model Zoo
We release three series of models, each tailored for specific use cases in visual geometry.

- 🌟 **DA3 Main Series** (`DA3-Giant`, `DA3-Large`, `DA3-Base`, `DA3-Small`) These are our flagship foundation models, trained with a unified depth-ray representation. By varying the input configuration, a single model can perform a wide range of tasks:
  + 🌊 **Monocular Depth Estimation**: Predicts a depth map from a single RGB image.
  + 🌊 **Multi-View Depth Estimation**: Generates consistent depth maps from multiple images for high-quality fusion.
  + 🎯 **Pose-Conditioned Depth Estimation**: Achieves superior depth consistency when camera poses are provided as input.
  + 📷 **Camera Pose Estimation**:  Estimates camera extrinsics and intrinsics from one or more images.
  + 🟡 **3D Gaussian Estimation**: Directly predicts 3D Gaussians, enabling high-fidelity novel view synthesis.

- 📐 **DA3 Metric Series** (`DA3Metric-Large`) A specialized model fine-tuned for metric depth estimation in monocular settings, ideal for applications requiring real-world scale.

- 🔍 **DA3 Monocular Series** (`DA3Mono-Large`). A dedicated model for high-quality relative monocular depth estimation. Unlike disparity-based models (e.g.,  [Depth Anything 2](https://github.com/DepthAnything/Depth-Anything-V2)), it directly predicts depth, resulting in superior geometric accuracy.

🔗 Leveraging these available models, we developed a **nested series** (`DA3Nested-Giant-Large`). This series combines a any-view giant model with a metric model to reconstruct visual geometry at a real-world metric scale.

### 🛠️ Codebase Features
Our repository is designed to be a powerful and user-friendly toolkit for both practical application and future research.
- 🎨 **Interactive Web UI & Gallery**: Visualize model outputs and compare results with an easy-to-use Gradio-based web interface.
- ⚡ **Flexible Command-Line Interface (CLI)**: Powerful and scriptable CLI for batch processing and integration into custom workflows.
- 💾 **Multiple Export Formats**: Save your results in various formats, including `glb`, `npz`, depth images, `ply`, 3DGS videos, etc, to seamlessly connect with other tools.
- 🔧 **Extensible and Modular Design**: The codebase is structured to facilitate future research and the integration of new models or functionalities.


<!-- ### 🎯 Visual Geometry Benchmark
We introduce a new benchmark to rigorously evaluate geometry prediction models on three key tasks: pose estimation, 3D reconstruction, and visual rendering (novel view synthesis) quality.

- 🔄 **Broad Model Compatibility**: Our benchmark is designed to be versatile, supporting the evaluation of various models, including both monocular and multi-view depth estimation approaches.
- 🔬 **Robust Evaluation Pipeline**: We provide a standardized pipeline featuring RANSAC-based pose alignment, TSDF fusion for dense reconstruction, and a principled view selection strategy for novel view synthesis.
- 📊 **Standardized Metrics**: Performance is measured using established metrics: AUC for pose accuracy, F1-score and Chamfer Distance for reconstruction, and PSNR/SSIM/LPIPS for rendering quality.
- 🌍 **Diverse and Challenging Datasets**: The benchmark spans a wide range of scenes from datasets like HiRoom, ETH3D, DTU, 7Scenes, ScanNet++, DL3DV, Tanks and Temples, and MegaDepth. -->

### 💻 Basic Usage

```python
import glob, os, torch
from depth_anything_3.api import DepthAnything3
device = torch.device("cuda")
model = DepthAnything3.from_pretrained("depth-anything/DA3NESTED-GIANT-LARGE")
model = model.to(device=device)
example_path = "assets/examples/SOH"
images = sorted(glob.glob(os.path.join(example_path, "*.png")))
prediction = model.inference(
    images,
)
# prediction.processed_images : [N, H, W, 3] uint8   array
print(prediction.processed_images.shape)
# prediction.depth            : [N, H, W]    float32 array
print(prediction.depth.shape)  
# prediction.conf             : [N, H, W]    float32 array
print(prediction.conf.shape)  
# prediction.extrinsics       : [N, 3, 4]    float32 array # opencv w2c or colmap format
print(prediction.extrinsics.shape)
# prediction.intrinsics       : [N, 3, 3]    float32 array
print(prediction.intrinsics.shape)
```

```bash

export MODEL_DIR=depth-anything/DA3NESTED-GIANT-LARGE
# This can be a Hugging Face repository or a local directory
# If you encounter network issues, consider using the following mirror: export HF_ENDPOINT=https://hf-mirror.com
# Alternatively, you can download the model directly from Hugging Face
export GALLERY_DIR=workspace/gallery
mkdir -p $GALLERY_DIR

# CLI auto mode with backend reuse
da3 backend --model-dir ${MODEL_DIR} --gallery-dir ${GALLERY_DIR} # Cache model to gpu
da3 auto assets/examples/SOH \
    --export-format glb \
    --export-dir ${GALLERY_DIR}/TEST_BACKEND/SOH \
    --use-backend

# CLI video processing with feature visualization
da3 video assets/examples/robot_unitree.mp4 \
    --fps 15 \
    --use-backend \
    --export-dir ${GALLERY_DIR}/TEST_BACKEND/robo \
    --export-format glb-feat_vis \
    --feat-vis-fps 15 \
    --process-res-method lower_bound_resize \
    --export-feat "11,21,31"

da3 auto assets/examples/SOH \
    --export-format glb \

```

The model architecture is defined in [`DepthAnything3Net`](src/depth_anything_3/model/da3.py), and specified with a Yaml config file located at [`src/depth_anything_3/configs`](src/depth_anything_3/configs). The input and output processing are handled by [`DepthAnything3`](src/depth_anything_3/api.py). To customize the model architecture, simply create a new config file (*e.g.*, `path/to/new/config`) as:

```yaml
__object__:
  path: depth_anything_3.model.da3
  name: DepthAnything3Net
  args: as_params

net:
  __object__:
    path: depth_anything_3.model.dinov2.dinov2
    name: DinoV2
    args: as_params

  name: vitb
  out_layers: [5, 7, 9, 11]
  alt_start: 4
  qknorm_start: 4
  rope_start: 4
  cat_token: True

head:
  __object__:
    path: depth_anything_3.model.dualdpt
    name: DualDPT
    args: as_params

  dim_in: &head_dim_in 1536
  output_dim: 2
  features: &head_features 128
  out_channels: &head_out_channels [96, 192, 384, 768]
```

Then, the model can be created with the following code snippet.
```python
from depth_anything_3.cfg import create_object, load_config

Model = create_object(load_config("path/to/new/config"))
```

    images=image_paths,
    batch_size="auto",  # Automatically selects optimal batch size
    target_memory_utilization=0.85,
)

# Fixed batch size
results = model.batch_inference(
    images=image_paths,
    batch_size=4,
)
```

## ❓ FAQ

- **Monocular Metric Depth**: To obtain metric depth in meters from `DA3METRIC-LARGE`, use `metric_depth = focal * net_output / 300.`, where `focal` is the focal length in pixels (typically the average of fx and fy from the camera intrinsic matrix K). Note that the output from `DA3NESTED-GIANT-LARGE` is already in meters.

- <a id="use-ray-pose"></a>**Ray Head (`use_ray_pose`)**:  Our API and CLI support `use_ray_pose` arg, which means that the model will derive camera pose from ray head, which is generally slightly slower, but more accurate. Note that the default is `False` for faster inference speed.
