Scan objects in 3D with this Arduino-controlled photogrammetry rig

Pictures can be a great way to record an object or project, but typically only does so in one perspective. In order to capture things in three dimensions, you’ll need to be able to snap multiple photos and stitch them together with software.
To take all the photos required for this process, “thomas_openscan” has come up with an automated device that rotates the object as needed, allowing him to capture images using a DSLR camera or even smartphone.

An early prototype is shown here, which actually moves a phone around the scanned object. The later, more refined version manipulates the object itself using an Arduino Nano and a pair of drivers to control a pair of bipolar stepper motors.
More information is available here and over on Thingiverse, and can be purchased or built depending on your needs.
