🔆 Introduction

• [24-9-19] Add scripts for preparing benchmark datasets.
• [24-9-18] Add point cloud sequence visualization.
• [24-9-14] 🔥🔥🔥 DepthCrafter is released now, have fun!

🤗 DepthCrafter can generate temporally consistent long depth sequences with fine-grained details for open-world videos, without requiring additional information such as camera poses or optical flow.

🎥 Visualization

We provide some demos of unprojected point cloud sequences, with reference RGB and estimated depth videos. Please refer to our project page for more details.

🚀 Quick Start

🛠️ Installation

1. Clone this repo:

git clone https://github.com/Tencent/DepthCrafter.git

2. Install dependencies (please refer to requirements.txt):

pip install -r requirements.txt

🤗 Model Zoo

DepthCrafter is available in the Hugging Face Model Hub.

🏃‍♂️ Inference

1. High-resolution inference, requires a GPU with ~26GB memory for 1024x576 resolution:

• Full inference (~0.6 fps on A100, recommended for high-quality results):

  python run.py  --video-path examples/example_01.mp4

• Fast inference through 4-step denoising and without classifier-free guidance （~2.3 fps on A100）:

  python run.py  --video-path examples/example_01.mp4 --num-inference-steps 4 --guidance-scale 1.0

2. Low-resolution inference, requires a GPU with ~9GB memory for 512x256 resolution:

• Full inference (~2.3 fps on A100):

  python run.py  --video-path examples/example_01.mp4 --max-res 512

• Fast inference through 4-step denoising and without classifier-free guidance (~9.4 fps on A100):

  python run.py  --video-path examples/example_01.mp4  --max-res 512 --num-inference-steps 4 --guidance-scale 1.0

🤖 Gradio Demo

We provide a local Gradio demo for DepthCrafter, which can be launched by running:

gradio app.py

🤝 Contributing

• Welcome to open issues and pull requests.
• Welcome to optimize the inference speed and memory usage, e.g., through model quantization, distillation, or other acceleration techniques.
