philnolan3d Posted June 2, 2009 Report Share Posted June 2, 2009 Not sure if you guys know about this one. It's basically a simple system to use a $25 laser level from the hardware store as a 3D scanner. I've been wanting to try it but lately even $25 is a lot of money. http://www.david-laserscanner.com/ A while back they did a whole episode of SYSTM on it: http://revision3.com/systm/laserscan Quote Link to comment Share on other sites More sharing options...
Advanced Member Oliver Thornton Posted June 3, 2009 Advanced Member Report Share Posted June 3, 2009 Wow, that is really pretty cool! Thanks for the heads-up Phil! -Oliver Quote Link to comment Share on other sites More sharing options...
philnolan3d Posted June 3, 2009 Author Report Share Posted June 3, 2009 No prob, BTW after posting that I looked at Home Depot's website and found a laser level there for $15. I don't know how good it is, but if you're really on a tight budget... Quote Link to comment Share on other sites More sharing options...
philnolan3d Posted May 21, 2011 Author Report Share Posted May 21, 2011 I finally got around to picking up a laser level and I'm getting ready to do my first scan. My camera's all calibrated, I just need to wait until the sun goes down so the laser light is visible enough. Here is the level I bought, I'll share how well it works. http://www.homedepot.com/h_d1/N-5yc1v/R-100375599/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053 Quote Link to comment Share on other sites More sharing options...
Advanced Member Digital777 Posted May 23, 2011 Advanced Member Report Share Posted May 23, 2011 I looked at the website samples and it seems really good, i know a lot of company's edit things to make them seem more impressive though so i am just wondering if it actually works well?

philnolan3d Posted May 23, 2011 Author Report Share Posted May 23, 2011 Well if you like you can watch this episode of he now cancelled show SYSTM, they go through the whole process with a guy who's just a user, no affiliation. http://revision3.com/systm/laserscan Quote Link to comment Share on other sites More sharing options...
Advanced Member parel Posted May 23, 2011 Advanced Member Report Share Posted May 23, 2011 A friend of mine has a David laser setup. One problem is that the Red Laser is not fine or bright enough. You need to scan in a dark room. You probably need a green laser to get a clean scan. Overall though- great value for money eventhough there is a lot of manual cleanup.

philnolan3d Posted May 23, 2011 Author Report Share Posted May 23, 2011 I found some tricks to improve my first test and also got a different camera to use but I'm not sure how good it will be since its old. I'm looking at getting a Kinect for mocap and I'm starting to wonder if that might be better for scanning. Quote Link to comment Share on other sites More sharing options...
Member cliveb Posted May 23, 2011 Member Report Share Posted May 23, 2011 Hi Phil, I have been using the DAVID program for a while and one of the great features is that there are two settings you can manually setup for the scan. The first is the texture camera acquisition and the scan camera acquisition. Both these settings use the camera setting function. What this means is that even if you have lights on in the background, you can set the scanning camera acquisition setting to darker ( bringing down the brightness, exposure ) while the texture camera setting remains at the original setting. The program will remember these for the whole of the scanning procedure I hope this makes sense and clarifies it a bit more. Cliveb Quote Link to comment Share on other sites More sharing options...
philnolan3d Posted May 23, 2011 Author Report Share Posted May 23, 2011 I think that does help. I just wish the full version wasn't so expensive. I don't see any other good way to re-assemble the pieces after scanning. Quote Link to comment Share on other sites More sharing options...
Member cliveb Posted May 23, 2011 Member Report Share Posted May 23, 2011 You can use Meshlab 1.30 which can align meshes automatically or manually http://meshlab.sourceforge.net Quote Link to comment Share on other sites More sharing options...
philnolan3d Posted May 24, 2011 Author Report Share Posted May 24, 2011 Oh Thank you I downloaded the latest Meshlab but I didn't know it could do that. Quote Link to comment Share on other sites More sharing options...
Advanced Member spacepainter Posted May 24, 2011 Advanced Member Report Share Posted May 24, 2011 Is there a big difference with the free and the pro version? Quote Link to comment Share on other sites More sharing options...
philnolan3d Posted May 24, 2011 Author Report Share Posted May 24, 2011 The free version cuts the resolution in half for the saved model, you also have no access to the Shapefusion part of the app, which stitches together all of your scans. Although, as cliveB said above you can apparently do that in Meshlab. This page has a chart showing the difference between free and pay: http://www.david-laserscanner.com/?section=Buy Unfortunately $280 is way out of my price range for something like this. Edit: I found this nice tutorial on combining the scanned meshes in Meshlab. http://www.youtube.com/watch?v=4g9Hap4rX0k Quote Link to comment Share on other sites More sharing options...
Advanced Member spacepainter Posted May 25, 2011 Advanced Member Report Share Posted May 25, 2011 Sounds like a pretty workaround. Quote Link to comment Share on other sites More sharing options...
