Picamera2 comes with a wealth of example code and detailed documentation to help beginners get started quickly. At the same time, developers can customize their development based on the examples in the documentation, creating unique applications.

Installing Picamera2

System Requirements

Picamera2 currently only supports Raspberry Pi OS Bullseye (or higher), compatible with all Raspberry Pi boards, from Pi Zero to Pi 4.

Installation Steps

1. 1. Update the System: Ensure your Raspberry Pi OS is up to date:

  sudo apt update
  sudo apt upgrade

1. 2. Install Picamera2: It is recommended to use apt for installation. If you have previously installed Picamera2 using pip, you need to uninstall it first:

   pip3 uninstall picamera2

Then install Picamera2:

   sudo apt install -y python3-picamera2

1. 3. Install GUI (Optional): If you need to use a graphical user interface, you can also install the Qt and OpenGL dependencies:

   sudo apt install -y python3-pyqt5 python3-opengl

Verify Installation

After installation, users can verify if the installation is successful by running some example code or checking the examples within the library.

Application Scenarios

Real-Time Monitoring

With Picamera2, you can easily build a real-time monitoring system to keep an eye on your home or workplace.

Camera Experiments

For educational institutions and researchers, Picamera2 can be used for image processing experiments, exploring the principles of computer vision and image analysis.

Creation and Sharing

Many makers use Picamera2 for video creation, making short videos, time-lapse photography, and more. You can easily set shooting parameters to capture moments in life.

Future Development

Picamera2 is still continuously iterating, and its development team promises to continuously fix bugs, improve stability, and add features that users demand. Feedback from the user community will also drive its evolution.

Conclusion

Picamera2 provides a powerful and flexible tool for using the Raspberry Pi camera, making data collection and video processing simpler and hassle-free.
