Raspberry Pi Handheld 3D Scanner

I’ve had some fun with photogrammetry recently and wanted to try out other techniques for 3D scanning. I’ve actually sort of accomplished S.L.A.M. during a hackathon using the PlayStation 4 camera and the Xbox One Kinect already, but I wanted something portable! With the new Raspberry Pi 4 debuting this year, I can finally accomplish this… sort of…
