Pretty cool stuff especially considering that it is home brew.

Oh yeah- its a free software (with a high res pro version) and all you need is a laser level and a webcam.

SWEET…gotta try me some of THAT

very excited about the technology, but wondering what kind of results I could get from the real (non freeware) version of the software with my current set-up.
It was cool to use the free software and get something out of it, but the results were not exactly amazing.

The overall fidelity and texture reminds me of the sneeze scans

or not?

scan was of this stapler



that looks hot

From the results we are having, the thinner the laser and the brighter the line, the better. Also make sure that the background plate is very close in size to the scanned object. I’ve been posting on my blog with some of our results.

Cool render BTW

fo SHO

I checked that out the other night, but just now saw the pretty damn good results your buddy is getting of that pig.

I picked up a $20 5mw Green laser (beam is 2-3mm at 1 m) That’s what I used for this. Are you having any decent results with the free software or do you really need to upgrade to the pro version to get any real fidelity? Basically just wanted to keep it on the cheap if at all possible, not sure I will try to take it much further if I have to throw much money at it.

keep us posted…thanks

Thats too large to get fine detail from what I have been reading at the david forum. You want 1mm or less. I have read a few people having luck with this laser. http://www.aixiz.com/shop/product_info.php?cPath=1_23&products_id=78

I should be getting it in a few days and will share my results. I also upgraded my webcam to a logitech quickcam pro 9000 so that I can scan at a higher res than 640x480 that my old cam was limited to.

The results from the stapler image look to me like your camera settings are not correct. This scattering of polygons occurs when the laser bounces off the backdrop back to the camera. You will need to lower your exposure and brightness settings. I found best results in my office at night when sunlight does not come in through the blinds behind my setup.

Download the second file on the page to see what your laser should look like when sweeping it over the object. http://www.david-laserscanner.com/?section=Downloads

I will try to post when I get my new laser setup.

Thanks for the response Eric!

I was a little trigger happy on the laser buying, thinking I’ll buy a green laser and that will be the end of it, then I started looking through the forum and saw that maybe 2-3mm beam was too wide…doh!

Thanks so much for the input, I look forward to seeing your results with the new laser and will tweak my camera settings in the meantime to see what kind of improvements I get, I have literally just done a couple scans that didn’t work with a super weak red laser and then the one (yay it actually worked) scan and haven’t had a chance to revisit and optimize, so maybe I’ll get something a little better, but still plant to upgrade.
