Description

I want to see how fast I can develop a single-camera (pi camera module v3) rig with a stepper motor controlling a turntable that rotates the model being scanned. The trick here is not to be super fancy with 100's of sensors and data inputs, quite the opposite. I want to see how accurate I can scan objects into 3D-printable models using only a camera and as many fixed and known parameters as possible.

Speed to be augmented with agentic AI coding companion. As it stands, I have a 3D printer, pretty much all the electronics I need.

Goals

• Design and print working/workable camera rig
• Design and print working/workable turntable (considering printing my own cylinder-style bearings as well)
• Assemble rig components into MVP assembly
• Develop application that can hook into existing tools, or leverage a library like openCV, to process 2D images into a 3D model.
• Iterate until models are good enough to 3D print.
