Laser Projection Vision System

September 2008

A project at GTRI FPTD I worked on involving combining a color vision system with a 2D laser projector.

Case Study about the project here:  Using Lasers to Identify Substandard Food.

With Python and OpenCV, I got the system to find contours with the camera, and tell the laser to draw them in real-time. The goal was to use this laser system as a module to another system that detected under-cooked sausage patties. The two systems combined detected, analyzed, tracked, and identified (with the laser) food on a conveyor belt that wasn’t cooked properly. The laser overlaid different patterns on the food product to indicate the quality of cooking.

 

See it in action!
