Small hobby project for an autonomous embedded device that can track things using a pan tilt system using the RaspberryPI.
The idea behind that is to be able to build a unofficial "Portal Sentry Turret: https://theportalwiki.com/wiki/Sentry_Turret".
There is a little bit of information in my blog about this project
Install the required packages:
pip3 install -r requirements.txt
Make sure the gpio daemon is started when the raspberry pi boots:
sudo systemctl enable pigpiod
A custom built "rtcom" library is used for communication.
It works by broadcasting endpoints on the network over UDP.
The UI is handle by the video_reader.py file. It should be run on a PC, not on the raspberry pi.
As of now, it diplays the feed from the follower.
python video_reader.py
Make sure the camera is enabled:
sudo raspi-config
interfacing options->camera->enable the camera
The controller requires a Coral USB Accelerator for embedded inference. https://coral.ai/docs/accelerator/get-started/.

Edit crontab for the user:
pi@turret:~ $ crontab -e
And add that line:
@reboot bash /home/pi/follower/start.sh > /home/pi/follower/start.log 2>&1
On the raspberry pi, run
python3 controller.py
