Summary

3d scanner info

David Cooper, Brown

they use canadian company called Shape Grabber also check out color scanner company

4 or 5 yrs ago, then upgrade

Camera + Scanning platform, new camera lser combo is now out, so they upgraded now 3 years old $60,000 -$70,000 for 2 heads with different range, resolution

Now, there are cheaper cameras, not sure how they compare regarding resolution and noise handling, as low as $10,000 but not sure how good they are

Should spend $30,000 - $40,000

2 heads:

15000 points per second

latest laser models are 150,000 points per second

Stripe-light are lower res, $10,000 , several mm

Also speak to

Larger architectural systems that scan up to 100feet also available.

Hi Christopher

We have an Eyetronics system that we are not %100 percent happy from. I am currently at the VAST conference in Italy (virtual reality and archaeology) and alot of the speakers are using a Minolta system which they seem to be happy about. The choice mainly depends on your application. If you want accurate measurements, laser scanning seems to be the best. Other systems are based on structured lighting, where you project a strip of light on the object and image it through a camera. Another solution is to use lots of cameras (cultural heritage center in Los Angeles seems to be doing that and seems quite successful) We were interested in getting texture information as well as the 3D point cloud and the system David has at Brown doesnt get texture. This is why we bought the Eyetronics system, but as I said Minolta seems to be a better choice (but quite more expensive) Fraunhofer institute also had a system which was good.

Hope this will help.

Christopher, Your choices will be limited with that budget; a lot of the better scanners begin about $50000 and work there way up to the $500000 level. We may be selling our scantech scanner, I am not sure just yet. This would be a good scanner to start with. It will give you a fairly large scanning envelope of about 24"x24". The resolution in about .3mm to point .5mm. You can control this to be larger if you have simple surfaces. We just move the pieces around when we need to scan larger models. I would suggest that you look up 3D scanners on the web. There are some smaller ones that would fit your budget, though the resolution may not be that great. Stay in touch..

Hi Christopher,

Thank you for your interest in ?ShapeGrabber. It was great talking to you earlier this morning. Based on the information you provided, I believe our portable PLM600 system would be ideal for your intended purpose. With this system you will be able to quickly digitize both small and large parts. The PLM600 system comes complete with a scan head of your choice, a 600mm high precision linear rail, motor, frame, high-end CAD computer, SG Central software, 1-year parts warranty, 1-year software maintenance, installation and on-site training. The price of the PLM600 system is $53,000 USD. As I've mentioned, we also extend a 20% educational discount to degree-granting institutions. For more information on this product, please visit our website at httphttp://www.shapegrabber.com/Portable2.shtml.

The choice of scan head will depend on several factors such as scan volume, accuracy, and resolution. From what you've told me so far, I believe the SG502 scan head would be ideal. More information on the specifications of our scan heads is located in httphttp://www.shapegrabber.com/ScanHeadsSG2.shtml.

As agreed, I have tasked myself to follow-up with you in mid-January. In the meantime, should you have any questions, please feel free to contact me directly.
