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. 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-hf")
model = PromptDepthAnythingForDepthEstimation.from_pretrained("depth-anything/prompt-depth-anything-vits-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"] Citation#
