This work presents Depth Anything V2. It significantly outperforms V1 in fine-grained details and robustness. Compared with SD-based models, it enjoys faster inference speed, fewer parameters, and higher depth accuracy.
We provide four models of varying scales for robust relative depth estimation:
| Model | Params | Checkpoint |
|---|---|---|
| Depth-Anything-V2-Small | 24.8M | Download |
| Depth-Anything-V2-Base | 97.5M | Download |
| Depth-Anything-V2-Large | 335.3M | Download |
| Depth-Anything-V2-Giant | 1.3B | Coming soon |

from transformers import pipeline
from PIL import Image
pipe = pipeline(task="depth-estimation", model="depth-anything/Depth-Anything-V2-Small-hf")
image = Image.open('your/image/path')
depth = pipe(image)["depth"]python run.py
--encoder <vits | vitb | vitl | vitg>
--img-path <path> --outdir <outdir>
[--input-size <size>] [--pred-only] [--grayscale]Options:
--img-path: You can either 1) point it to an image directory storing all interested images, 2) point it to a single image, or 3) point it to a text file storing all image paths.--input-size (optional): By default, we use input size 518 for model inference. You can increase the size for even more fine-grained results.--pred-only (optional): Only save the predicted depth map, without raw image.--grayscale (optional): Save the grayscale depth map, without applying color palette.For example:
python run.py --encoder vitl --img-path assets/examples --outdir depth_vispython run_video.py
--encoder <vits | vitb | vitl | vitg>
--video-path assets/examples_video --outdir video_depth_vis
[--input-size <size>] [--pred-only] [--grayscale]Our larger model has better temporal consistency on videos.

Note: Compared to V1, we have made a minor modification to the DINOv2-DPT architecture (originating from this issue). In V1, we unintentionally used features from the last four layers of DINOv2 for decoding. In V2, we use intermediate features instead. Although this modification did not improve details or accuracy, we decided to follow this common practice.
Please refer to metric depth estimation.
Please refer to DA-2K benchmark.
We sincerely appreciate all the community support for our Depth Anything series. Thank you a lot!
We are sincerely grateful to the awesome Hugging Face team (@Pedro Cuenca, @Niels Rogge, @Merve Noyan, @Amy Roberts, et al.) for their huge efforts in supporting our models in Transformers and Apple Core ML.
We also thank the DINOv2 team for contributing such impressive models to our community.
