Hi,

Im looking for a not too expensive 3dscanner, wich can produce acceptable results.

I already discovered 2 3dscanners for around 3000$

If you know other, cheaper or better 3dscanners or if you have experience with 3dscanners and can give me a tip, please let me know.

Maybe worth a try.

thank you.

this david-laserscanner looks very nice for the price of 399Euro. There are also some great examples in the gallery. Has anyone here tested it and can tell something about?

When it was brand new I took a line laser I had lying around (Wasserwaage) and gave it a try. Worked, but my webcam wasn't that great. Haven't tested it for maybe 3 years, I guess they made it even better till now (Germans btw).

There are a couple of projects using Blender and the Kinect.

I've been playing with the David scanner for a while and I'm quite impressed with it.

There is a very wide range in price versus quality so depending on your needs you may be able to do everything you need with the free version and cheap equipment or you might need to look at a better camera/laser/etc. It all depends on what you're looking to get out of it. Just a guess but I think a person could easily create a relatively high quality David scanner for less than $1000 USD depending on your shopping abilities. For example, I got a used ImagingSource firewire color CCD (DFK_31AF03) for about $300 off of ebay. I paid about $175 for a 5mw green line laser. Other equipment too, but I think I have about $1000 into my system and I'm sure I could've got that price down more if it wasn't for trial and error.

Seeing as you're in Germany I think you would be best served by contacting the David developers and seeing what they would recommend. I know some of their German members have built turnkey systems for people, so you might be able to get a good deal or possibly even borrow someone's system for testing to see if it fits your needs.

I've also been looking at the Kinect and I see that becoming a very popular and affordable option very soon. Not sure of the range of detail it's capable of though. I did see that someone on BlenderNation created a realtime scanner using the Kinect. I could see this giving the average person the ability to do desktop motion capture. Pretty amazing stuff.

Sorry for such a long post, but hope it helped somewhat.

thank you all very much for your help. This kinect project looks interesting.

@ pottersfriend: Why have you choosed a green laser instead of a blue or red? And why have you choosed a more expensive camera with a lower resolution that the camera in the starter package? Im sure you had a reason for this, just try to understand.

Im nearly sure that I will try it out, I just dont know which camera and laser I should buy.

One more thing... Do I need the pro version of their software or can I work with the free version also?

Svenart,

The reason I chose the CCD camera is because, even though it's max resolution (1024x768) is lower than the QuickCam Pro 9000 (1600x1200) it has a much higher frame rate of 30fps versus 5fps. This can really speed up your scan times.

As for the green laser the reason is that the way the CCD sensor "sees" colors. Typically it is 25% Red, 25% Blue, and 50% Green, so accentually it's able to capture more pixels with a color CCD and a green laser. If you had a monochrome CCD the color laser wouldn't matter.

If you're not in a huge rush I would recommend starting simple, using the free version, the QuickCam Pro 9000 and one of the affordable red lasers shown in the David store. It's a relatively cheap way to start and see if it's going to work for you. David scanning is a little finicky at first since it can be hard to get camera settings just right but with a little patience it can be quite powerful. Also, the free version only let's you save files out at a lower resolution, but within the software it does display it at the higher scanned resolution. Definitely get on their forum and ask questions, they're all very helpful.

What type/size of objects are you wanting to scan? Also be aware that coating objects with some sort of matte white coating is most likely required so the laser won't be effected by reflection or refraction as much.

Maybe worth a try.

had a look at this some time back and it's VERY impressive :]
it's just as good as 3Dscanners that cost 4 times as much, even better!
