FabScan - Affordable 3D Laser Scanning of Physical Objects

Bachelor thesis by Francis Engelmann, supervised by René Bohne
Also see the project on GitHub and Thingiverse.
Have a look at out FabScan Google Group.

Features

• A scan can be performed by one click.
• Export point clouds as PTS, PLY and PCD.
• Automatic generation of ready-to-print STL and SCAD.
• Complete Do-It-Yourself Projects. All the schematics for the parts are available for download.
• Hardware uses a rotating line laser and a turntable allowing automated 360degree scans.

Needed Hardware Parts

1x Logitech Quickcam Pro 9000 http://www.logitech.com/de-de/support-downloads/downloads/business-products/devices/4597

1x Line-Laser here.
2x Stepper Motor http://www.watterott.com/de/Pololu-A4988-Schrittmotortreiber
2x Stepper Motor Driver http://www.pololu.com/catalog/product/1201
1x Arduino Uno http://arduino.cc/en/Main/arduinoBoardUno
6x MDF 5mm 30cmx60cm

Mister Bear and his cloned brother scanned in the FabScan and 3d-printed with ABS plastic.

Version History of the different prototypes

Prototype 1

The point cloud generated by the first protoype.

Prototype 2

Some scanning results of second prototype, showing the generated pointcloud and one transformed into a mesh using powercrust algorithm.


Download the pointcloud for the duck:
duckHQ.pts File containing just the x y z coordinates of the points, without color.
duckHQ.pcd Point Cloud Data from PCL with color.



Screenshot of the GUI after a scan.

Prototype 3

Moving the laser during a scan minimizes the laser shadow problem.
The scanning resolution for these scans was turned down in order to speed up the scanning process but the improved quality of the handle is clearly visible!
