REPRAP 3D Scanner? December 04, 2014 04:34PM |

I have been thinking. Not a good thing right?
Most of us have 3d printers, and some have built their own 3d scanners, however nothing has been structured. I have some ideas for a reprap style 3d scanner.
The idea is simple. Requires mostly 3d printed parts and the final post processing gets done.
1 - raspberry pi
2 - pi camera
3 - stepper controller used via the 4 gpio pins on the PI
4 - Laser(s)
5 - 3d Printed parts.
6 - Misc hardware
The idea is to have the pi as a standalone solution controlling a nema 17 at certain intervals and taking pictures based on the speed rate while dumping them on a shared drive via wifi/ethernet or to a USB drive. Once done pumping the pictures into something like meshlabs and creating high resolution 3d scans.
Any takers? I have no problem doing the groundwork for the hardware and making the parts open source, I have no issue building the PI image preloaded with the required packs, I have some reservations on writing the controll software. Idealy this thing would have a single button that simply trigers a controll script.
Imagine this, nema 17 1.8 degree per step, while connected to a 20T pulley which is connected to a 40T pulley giving you roughly 400 steps per rotation, if so configured we can have 400 5-megapixle images dumped to storage, while this would hammer a 3d processing with current software, it should be possible to get a decent scan from this.
Any takers?

En se servant de ces deux expériences :
On peut, dé-lors relancer le projet SPLINESCAN (http://reprap.org/wiki/SplineScan).
Les pointeurs lasers sont bon marché;
la USB caméra PS3 Eye, posséde des détecteur de mouvement.
Elle coûte 10$ , sur ebay.
Alors si on monte le pointeur lasers sur un axe, et que l'on automatise le déplacement du faisceau (avec nema 16 arduino) ;
On a un balayage régulier de l'objet.
On le mesure numériquement…
En parallèle, on film ce même objet avec au moins trois caméras, placé sur les trois axes principales (X,Y,Z).
On compiles les images des différentes caméras, pour obtenir l'image 3D finale.
et avec un sous programme la faire orbiter autour de l'objet a scanner (petit objet).
Prise de vue sur 5 faces, reconstitution de l'image 3D par photogrammétrie.
