Set up the environment

To set up the environment for running the SpaTrack model, follow these steps:

Clone the Repository:

# clone the code
git clone https://github.com/henry123-boy/SpaTrackerV2.git
cd SpaTrackerV2

# optionally download the example data to run the examples
# Note: This will slowdown the clonining process, as it includes large files.
git submodule update --init --recursive

Create a Virtual Environment: It's recommended to use a virtual environment to manage dependencies.
```
conda create -n SpaTrack2 python=3.11
conda activate SpaTrack2
```

Install Dependencies:

Install the torch dependencies pip (tested with torch2.4).

python -m pip install torch==2.4.1 torchvision==0.19.1 torchaudio==2.4.1 --index-url https://download.pytorch.org/whl/cu124

Install the required Python packages using pip.

python -m pip install -r requirements.txt

By following these steps, you should have a working environment ready to run the SpaTrack model.

Quick Start

Here are two examples of how to use SpaTrack2.

Type1: Monocular video as input (Example0)

python inference.py --data_type="RGB" --data_dir="examples" --video_name="protein" --fps=3

Type2: RGBD video + Camera poses as input (Example1)

We provide an example with Depth and Camera poses from MegaSAM. First, download the examples via:

sh scripts/download.sh

Then run inference with the command with below:

python inference.py --data_type="RGBD" --data_dir="assets/example1" --video_name="snowboard" --fps=1

Visualize your results

Guidance will be displayed in the terminal after running inference.py.

🌟 Recommended: Gradio Demo with SAM 🌟

Please follow the instructions in the app_3rd README to configure the dependencies. Then, install the required packages:

python -m pip install gradio==5.31.0 pako

Our Gradio demo enables users to easily track points on the target object. Just try:

python app.py
