Roast Watcher

A Rust-based computer vision system for reading and decoding 7-segment displays using OpenCV. Designed to extract numerical data from a video of a coffee roasting cycle.

The current implementation is designed specifically for a Java Master 2002 fluid bed coffee roaster, which has two PID controllers with readouts for air temp and bean temp.
