This project is a remix of the fantastic:
- Adafruit / Phillip Burgess (Paint Your Dragon)'s Animated Snake Eyes for Raspberry Pi
- Nathan Jennings / Real Python guide to Socket Programming in Python (Guide)
- Adrian Rosebrock's motion detection tutorial
- Three Raspberry Pi's
- Two HDMI screens which can support 1920x1080 pixels
- A Raspberry Pi camera for the motion detection
The server needs to have the camera interface enabled.
You do not need the Adafruit Snake Eyes Bonnet. This remix only supports HDMI.
These are abbreviated installation instructions. See INSTALL.md for more complete instructions.
Run the following script to install the code on each of the three Pi's. Set one to LEFT EYE, one to RIGHT EYE, and the one with the camera to EYE SERVER
cd ~
curl https://raw.githubusercontent.com/PaulZC/Pi_Eyes/master/installer.sh >installer.sh
sudo bash installer.sh
The code is installed into /boot/Pi_Eyes
If you want to stop the code running on boot:
sudo nano /etc/rc.local
and comment out the line at the end of the file (e.g.) #python3 eye_left_client.py
- Start the eye server first (so the eye clients can find it)
- Then start the two clients
All being well, the eyes should start random movement. They will track motion when the camera sees it.
Edit the code and change the host IP address to 127.0.0.1 for local testing on a single Pi.
Raspberry Pi 4 can just about run both eyes and the server at the same time (but not at 1920x1080).
You can remove the eye window banner by right clicking in the banner and selecting Un/Decorate.
At the time of writing, you will need to run the server from the command line using the following due to an issue with OpenCV 4.1.1.26
LD_PRELOAD=/usr/lib/arm-linux-gnueabihf/libatomic.so.1 python3 eye_position_server.py

Enjoy!
