Prompt-Depth-Anything-Vits-Transparent

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

import requests
from PIL import Image
from transformers import PromptDepthAnythingForDepthEstimation, PromptDepthAnythingImageProcessor

url = "https://github.com/DepthAnything/PromptDA/blob/main/assets/example_images/image.jpg?raw=true"
image = Image.open(requests.get(url, stream=True).raw)


image_processor = PromptDepthAnythingImageProcessor.from_pretrained("depth-anything/prompt-depth-anything-vits-transparent-hf")
model = PromptDepthAnythingForDepthEstimation.from_pretrained("depth-anything/prompt-depth-anything-vits-transparent-hf")

prompt_depth_url = "https://github.com/DepthAnything/PromptDA/blob/main/assets/example_images/arkit_depth.png?raw=true"
prompt_depth = Image.open(requests.get(prompt_depth_url, stream=True).raw)

inputs = image_processor(images=image, return_tensors="pt", prompt_depth=prompt_depth)
with torch.no_grad():
    outputs = model(**inputs)
post_processed_output = image_processor.post_process_depth_estimation(
    outputs,
    target_sizes=[(image.height, image.width)],
)

predicted_depth = post_processed_output[0]["predicted_depth"]
