Depth

🚀 Depth Anything V2 Base – Transformers Version

Depth Anything V2 is a highly capable monocular depth estimation (MDE) model trained from a large amount of synthetic and real images, offering fine - grained details, robustness, efficiency, and excellent fine - tuned performance.

🚀 Quick Start

Depth Anything V2 is trained from 595K synthetic labeled images and 62M+ real unlabeled images. It provides the most capable monocular depth estimation (MDE) model with the following features:

• more fine - grained details than Depth Anything V1
• more robust than Depth Anything V1 and SD - based models (e.g., Marigold, Geowizard)
• more efficient (10x faster) and more lightweight than SD - based models
• impressive fine - tuned performance with our pre - trained models

This model checkpoint is compatible with the transformers library.

Depth Anything V2 was introduced in the paper of the same name by Lihe Yang et al. It uses the same architecture as the original Depth Anything release, but uses synthetic data and a larger capacity teacher model to achieve much finer and robust depth predictions. The original Depth Anything model was introduced in the paper Depth Anything: Unleashing the Power of Large - Scale Unlabeled Data by Lihe Yang et al., and was first released in [this repository](https://github.com/LiheYoung/Depth - Anything).

✨ Features

• Fine - grained details: Offers more fine - grained details compared to Depth Anything V1.
• Robustness: More robust than Depth Anything V1 and SD - based models.
• Efficiency: 10x faster and more lightweight than SD - based models.
• Fine - tuned performance: Demonstrates impressive fine - tuned performance with pre - trained models.

📚 Documentation

Model description

Depth Anything V2 leverages the DPT architecture with a DINOv2 backbone.

The model is trained on ~600K synthetic labeled images and ~62 million real unlabeled images, obtaining state - of - the - art results for both relative and absolute depth estimation.

Intended uses & limitations

You can use the raw model for tasks like zero - shot depth estimation. See the [model hub](https://huggingface.co/models?search=depth - anything) to look for other versions on a task that interests you.

💻 Usage Examples

Basic Usage

Here is how to use this model to perform zero - shot depth estimation:

from transformers import pipeline
from PIL import Image
import requests

# load pipe
pipe = pipeline(task="depth-estimation", model="depth-anything/Depth-Anything-V2-Large-hf")

# load image
url = 'http://images.cocodataset.org/val2017/000000039769.jpg'
image = Image.open(requests.get(url, stream=True).raw)

# inference
depth = pipe(image)["depth"]

Advanced Usage

Alternatively, you can use the model and processor classes:

from transformers import AutoImageProcessor, AutoModelForDepthEstimation
import torch
import numpy as np
from PIL import Image
import requests

url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image = Image.open(requests.get(url, stream=True).raw)

image_processor = AutoImageProcessor.from_pretrained("depth-anything/Depth-Anything-V2-Large-hf")
model = AutoModelForDepthEstimation.from_pretrained("depth-anything/Depth-Anything-V2-Large-hf")

# prepare image for the model
inputs = image_processor(images=image, return_tensors="pt")

with torch.no_grad():
    outputs = model(**inputs)
    predicted_depth = outputs.predicted_depth

# interpolate to original size
prediction = torch.nn.functional.interpolate(
    predicted_depth.unsqueeze(1),
    size=image.size[::-1],
    mode="bicubic",
    align_corners=False,
)
