as his setup works without a projector (which I thought was a tad
expensive).
About a year ago I made my own prototype...
As I didn't have a stepper motor I just span the the laser stripe by hand.
I wrote some quick code to work out the angle the laser is pointing from
the image.
I got my laser stripe from a cheap Jigsaw - Yes I was walking around a
hardware store and thought .oO "cool there's a cheap laser stripe with a
free powertool attached" :-)
As a prototype it seemed to work but I only saved the range data as an
image that got rather corrupted by the compression.
I've since got fedup with Java on Windows and this week have set myself
the task of rewriting in C on Linux.
Here's a scaled down version of the range image I got.
I tried yesturday to create a height field out of it but it didn't
really go to plan :-(
