With this report I would like to present my scan equipment to you.
For some time I am working with the David scanner, my scanner scans are very good and I use the data for milling.
I hardly use the laser, because the SL scanning provides beautiful und fast results.
Since I wanted to simplify the steps I've built a remote control, which makes several steps easier. Now it is possible to scan from the PC or remote control.
Furthermore, a turntable is driven to be able to pivot and move.
The remote control and the turntable are controlled by an Arduino Uno communicating with the PC and David.
The software for the Arduino is http://wiki.david-3d.com/the_open_hardware_project
of David "The Open Hardware project."
I have rewritten the software for my personal needs. It was very hard work, as my programming skills are very low limited. The software now works error free with the remote control.
Now I will tell you the scan sequence with the remote control.
Calibration of the camera and projector and then switch in the "Light Structures
Folder " (switch .)
1 ) On the remote, press " START SCAN " .
The scan is performed.
2 ) Press the button "LIST AND TABLE"
The scan is listed and Turnable motor rotates the object 45 degrees
3 ) A beep sounds, indicating that this scan is complete
This operation is carried out 8 times , and the object is completely scanned.
The advantage is that I can always stay with the object and not always with the mouse or the keys have to click around on the PC.
Important for scanning objects which are valuable and are rotated by the motor.
The fusion is carried out in a conventional manner .
With the key " relief" following happens .
1 ) , the scanning head is created as described above and the object is rotated further by 45 degrees CCW .
2 ) The second Scan is made as described above.
3 ) Next, push the " relief" button and the turnable motor rotates the object by 135 degrees CW .
4 ) The third scan is made and the object is again rotated 45 degrees CCW and returns to its normal Position.
Usually only 3 scans are needed for a relief.
I’ll try to change the software further, becausesoftware further, because should once the merger be automated, David will be the first choice.
The rig, also constructed by me for my camera and projector, is very helpful
This rig can be installed vertically or horizontally.
All angles for all object sizes can be adjusted infinitely variable.a recording for conversion lenses . Now I can approach the object up to 40 mm-
Therefore I use 2 Logitech 9000 Kameras. One of them I have rebuilt with a zoom lens. Caution !! If the optics of the platinum of the Logitech is removed, the infrared filter will be missed and the colours are completely distorted.
Therefore I have dismantled a defective camera and built out the infrared filter and placed it on the sensor of the Logitech 9000.
Now the colours a super again.
As a third camera I use the Canon 600D.
"ATTENTION" ! Very important is the grounding of the tripod to the ground of the Arduino and the main ground .
When I didn’t have the grounding the Arduine temporarily lost its COM connection or the computer crashed. The PC had to be restarted. These errors are now never occurred again .These errors never occurred again.
