			\|abstract=In Duke University’s Mechanical Engineering Department, we developed a tabletop ice surface to demonstrate collision mechanics as a teaching lab exercise. The intention was to mimic the ice surface used in the sport of curling and measure the position of colliding granite stones versus time. The surface was created using a chiller pumping a subzero ethylene glycol and water mixture through copper tubes sandwiched between aluminum plates. Data acquisition was done using a webcam mounted above the surface and LabVIEW Vision.

Can I take a video? Can I playback? Can I identify the same object through multiple frames of a video? Can I calibrate pixels to distance? Can I track multiple objects at once? I’ll also talk about the many ways that I failed along the way (why is it confusing my two objects??) before reaching the final application and the subsequent lessons learned.

My approach was to play with each of these features in a “sandbox” before implementing them in the final application. At GDevConNA 2022, Katya Prince gave a fantastic presentation on machine vision. My presentation would echo similar points with regard to machine vision tips and tricks; however, I’d focus more on the problem-solving approach and hone into some of the lower level functions rather than use the Vision Assistant.
