Prompt-Depth-Anything-Vits

Introduction

Prompt Depth Anything is a high-resolution and accurate metric depth estimation method, with the following highlights:

• using prompting to unleash the power of depth foundation models, inspired by success of prompting in VLM and LLM foundation models.
• The widely available iPhone LiDAR is taken as the prompt, guiding the model to produce up to 4K resolution accurate metric depth.
• A scalable data pipeline is introduced to train the method.
• Prompt Depth Anything benefits downstream applications, including 3D reconstruction and generalized robotic grasping.

Installation

git clone https://github.com/DepthAnything/PromptDA.git
cd PromptDA
pip install -r requirements.txt
pip install -e .

Usage

from promptda.promptda import PromptDA
from promptda.utils.io_wrapper import load_image, load_depth, save_depth

DEVICE = 'cuda'
image_path = "assets/example_images/image.jpg"
prompt_depth_path = "assets/example_images/arkit_depth.png"
image = load_image(image_path).to(DEVICE)
prompt_depth = load_depth(prompt_depth_path).to(DEVICE) # 192x256, ARKit LiDAR depth in meters

model = PromptDA.from_pretrained("depth-anything/prompt-depth-anything-vits").to(DEVICE).eval()
depth = model.predict(image, prompt_depth) # HxW, depth in meters

save_depth(depth, prompt_depth=prompt_depth, image=image)
