I have a Looking Glass Portrait 3D Holographic Display, and I wanted a quick way to import 3D images into the display system. The Oak-D Lite attached to a raspberry pi running Luxonis OpenCV is one way to achieve this. However, this setup has lots of cables and needs power to be portable, so I put together a build which turns it into a portable camera.
The camera consists of a Raspberry pi 4B, 4 in. touchscreen display, power board with 4000mAh Li-ion battery, mounting plates, cables, and, of course, the Oak-D Lite AI camera.
The system outputs 1440 X 2160 pixel RGBD PNG files which have a left half RGB image and a right half greyscale depth image "heat map" where brighter objects are closer. These files are then imported into a Windows PC running Looking Glass HoloPlay Studio software which converts the file into a holographic display image on the Portrait display.
Here is the full documentation on the Prusa Printables website if you want to make your own 3D camera.
