Topic: Atlas 3D mods for multi-angle scans
For the longest time I've been thinking of doing a mod where I can scan an object from multiple angles easier and more accurately than I'm currently doing.
The first idea I had was to put the turntable on some kind of gimbals that would allow me to tilt the model at any angle toward the camera, while still maintain the center focus. The problem was the logistics being the model clamping method while still providing a way to rotate the entire contraption on its axis. While it can be done, I realized that there's actually a simpler solution...
...move the camera. Moving the camera on a vertical arc who's radius doesn't change, would allow it to always point to the center of the table. So the only requirement is that I make the camera and lasers modular from the rest of the scanner.
Here is a quick view of what I have in mind. The rail radius is wrong at the moment (half of what it should be), but you get the idea of what I'm trying to do. The plan is to allow 45° of vertical movement.
At the same time I wanted to mod the laser holders to allow for easier and finer adjustments, and the rack and pinion gimmick will allow me to change the spread between the lasers.
The only thing I haven't thought through yet, is the connection between the camera and the Pi. I will obviously need a longer Flex PCB, so I'll have to source that, or alternately come up with a wiring harness. Perhaps Uriah can suggest a source for a longer PCB.
I'll post more photos as the project moves along. At the moment it's all in the design phase.
