Hi *,

yesterday I've tried to scan a small embossment with a probe and G38.2-commands.
This scan was 30x60mm and took several hours in a 1mm-resolution.
The result is recognizable as an angel - but not really usable.....

I think, it should be possible, to use a line-laser (mounted on Z - like in the left picture)
and an HD-cam (in a fixed position) - and now move the laser-line with the X-axis
through the model and take a picture at every step.
With the resulting pictures, it should be possible, to generate a similar "dot-cloud" in a
higher resolution. (and much faster).

Has anyone tried to do this - or is there already an existing resolution?

regards

wicki

I have used David3D laser scanning software, it works by hand. Freeware has limited resolution output. I would assume it works while mounted on a CNC. It needs a calibration box, the last time I used it.

You would get a much better results in about 30 seconds with just laser line scanning it by hand using David3D than what you have right now. It will output an .obj file (vertexes or something) and can be manipulated in Meshlab.
