From the project
A project made mostly in python to classifie color caps using OpenCV
A mechatronic machine that classifies soda-bottle caps by color from a camera feed and physically sorts them into per-color outputs in real time. It combines computer vision (OpenCV on a Raspberry Pi), finite-state-machine firmware on an Arduino / ATmega328P, custom PCBs, and 3D-printed mechanical parts.
