I’ve been developing fully automated 3D scanner. Up until recently it was operated using a $15 webcam. This is an updated prototype of my newest head unit. I’ve been developing multiple revisions to this since this model but I figured I’d share this model with people though in case they want to toy with it themselves. Aside from the pi (which it can run without) most of the devices are relatively cheap and cost under $130 dollars all together. All the bolts are 1/4 half inch hex cap screws that go into 1/4 threaded heat inserts.

Current Parts Listed Below

ELP Synchronized Dual Lens Stereo Camera Model Number B083JSDD97 (Make sure you get the one WITHOUT lens distortion).

Benewake TFMini-S

Embedded Mega2560

Raspberry Pi 4 (8GB)

Inland Raspberry Pi 4 B Camera Webcam

a ton of 1/4 heat pressed threaded inserts (don’t judge it’s what I had!)

1/4 1inch hex cap bolts

This is the first revision of my fully automated 3D scanner. It was constructed with spare 3D printer parts I had laying around at the time. I’m currently working on a better one that is more modular features a laser array, range finder and duel cameras capable of better depth estimation. This current model was a very crude device I whipped together years ago to see if I could fully automate moving the camera around on a given path. The software I created for it allows the user to set a path for the camera to scan over an object and upload the results to a designated shared server space. The information can the be freely shared among designated users to allow teams of people to share their scans quickly and easily. The scanner itself leaves detailed information not only on the website but also in the meta data of the image. This makes creating point cloud maps that have more uniform camera distance information.
