pin(gpong)ball
Object Contour tracking in OpenCV and openFrameworks


pin(gpong)ball is a customizable projected pinball machine, with physical and digital parts. 

Players place physical moving parts that anchor digital bumpers with physics simulations. 

Once set up, they can play pinball.


I’ve been looking for ways for the physical to interact with the digital. 

In this early prototype, I used contour detection, and turned contours into colliders.


I detect the plastic pieces using their unique areas, assigning a range of values so that the camera can identify each under changing light settings.

Then I add cartoon bumpers to give the objects a personality.

You can see me playing with simple Lego controllers here.

In this project I used laser cut shapes from my Circular Rhythm Machine project, but these could easily be things you find around the house.

Developed in Openframeworks (C++), using ofxBox2d, ofArduino (StandardFirmata), ofxCV and ofKinect libraries. More info on Github. Built mostly in a hotel room during my quarantine after my flight from NYC.
