# Polytheremin LabView
[← Back to main repository](https://github.com/MiCyg/PolyTheremin.git)
---
# Description
More details are available in the [PolyTheremin repository](https://github.com/MiCyg/PolyTheremin) (currently under development).
This application integrates and tests acquisition and processing techniques while collecting data to support the development of a decorrelation algorithm. It uses the [PolyTheremin testing platform](https://github.com/MiCyg/PolyTheremin_Hardware) to detect hand gestures and measure distances between fingers and proximity sensors.
Hand movement detection is performed using the [Mediapipe library](https://github.com/google-ai-edge/mediapipe). To simplify setup, an installer has been provided to install the required Python version and dependencies.
---
# Before Launching LabVIEW
Run the [installation script](pythonInstallation.bat) to set up the correct Python version, create a virtual environment, and install the Mediapipe library.
[PolyTheremin Installation](https://github.com/user-attachments/assets/24161088-da3a-4458-9bec-f73b979741b2)
If the script fails to run, you can contact me for assistance or manually install the required dependencies:
1. Install **Python 3.10.0**.
2. Create a virtual environment named `mp_env` in the `vision/python/` folder.
3. Install the Mediapipe library in the `mp_env` environment.

---
# Application Window Description
## Setup
- **Proximitor Parameters**: Configure the cDAQ channels, sample rate, and buffer size. Default values may not be optimal, so it's recommended to adjust them.
- **Output Sound Format**: Select your audio output device.
- **Proximitor Scaling**: Each proximitor can be independently scaled to match your hardware and heterodyne generator.
- **Scaling Offset**: Add an offset to proximitor measurements.
## Dac
Displays a measurement graph for testing purposes.
## Vision
- **Camera Source**: Select the camera input.
- **Test Button**: Test the video feed from the camera.
- **Antenna Selector**: Choose antenna positions by clicking on the video pane.
- **Reverse Fingers**: Adjust the hand direction.
- **Ant Distance**: Calibrate the real distance (in mm) by the average video distance (in px) to calculate real distances between fingers and antennas.
- **FPS**: Displays the frames per second.
## Correlation
Displays a correlation plot for testing purposes.
## File Saver
- **File Save Button**: Start and stop data acquisition to a file.
- **File Path**: Select the TDMS file path.
