Routout CNC - DAVID- Laserscanner
Create 3D laser scans for your Mill / Router (Stl files can then be processed in MeshCam)
Description and Specification.
Features ( DAVID-Laserscanner / DAVID-Shapefusion)
DAVID-Laserscanner is a very low-cost system for contact-free scanning
of 3d objects. The only hardware requirements are a simple commercial
hand-held laser and a standard camera.
Compatible to most cameras with Microsoft Windows drivers (WDM):
You can use nearly every MS-Windows compatible camera with WDM support,
like your web-cam or fire-wire camera. You can even use your camcorder
if you can connect it to your PC (and if you have suitable WDM drivers).
Precise and automatic camera calibration:
It is not possible to get accurate 3d data with an uncalibrated camera.
Fortunately DAVID provides a well-integrated and easy to use calibration
for automatic computation of the camera's pose and focal length, as well
as for compensation of radial lens distortions. Therefore you can accurately
scan your objects with absolute scale.
Data smoothing and interpolation:
By moving the laser like a paintbrush, you can sweep over the object until
the scan results are smooth and all gaps are filled. Beside that, you
can use the gap interpolation and smoothing filters of DAVID to refine
your scans.
Texture support:
You can grab a camera shot that will be used as texture. The texturized
3d model can be inspected in the 3d window. Furthermore DAVID exports
texture coordinates, which allows you to import the textured object in
third-party software.
Integrated 3d viewer:
Inspect your 3d model right after scanning with the integrated OpenGL-based
3D viewer of DAVID.
File export:
Save your scanned object as Alias Wavefront OBJ file. The OBJ-format is
an well-established plain text format for triangle meshes and is supported
by many 3d applications. (Further file formats can be exported with DAVID-Shapefusion.)
What do I need to build a 3D scanner?
- A camera (e.g. web cam)
- A hand-held line laser (starting at €12.90)
- Two plain boards in the background
- A Windows PC
- 'DAVID-Laserscanner' or DAVID-Shapefusion Software.
How does scanning with DAVID work?
- Set up background and camera
- Calibrate your camera with one click
- Start scanning by sweeping the laser line over the object
- Export your result to .OBJ
- Optional: Automatically stitch several scans/meshes with DAVID-Shapefusion
and export .STL or .PLY
Supports Popular Formats
DAVID-Laserscanner supports OBJ in it's free version but also supports
additionally STL and PLY when purchasing the DAVID-Shapefusion licence.
These two formats enable compatibility with virtually every CAD package.
MeshCAM can be used to process the file created with DAVID-Laserscanner.
Please note you will need DAVID-Shapefusion licence to process the file in MeshCam.
DAVID-Shapefusion software is supplied on a flash USB Drive. You will need a free USB drive to run the software.
