*New DAVID Version 3*
Voila: After more than a year of development, DAVID 3.0 is now available!
The most important innovation:
DAVID is the first and only software that supports both, "classic" Laser Scanning AND Structured Light Scanning! The Structured Light method is presented below.
Also, the completely new user interface makes DAVID3 more flexible, extendable and user-friendly.
Of course the new version is compatible to the same hardware:
cameras, lasers, calibration patterns...
As always we offer a Free Version for everyone. Please feel free to test everything! Only saving results is limited. Download: http://www.david-laserscanner.com/?section=Downloads
If you would like to purchase a license, please open http://www.david-laserscanner.com/?section=Buy
Of course if you already own a DAVID 2.x license or original USB key, you can upgrade to DAVID 3 at a lower price. Upgrade procedure details can be found at http://www.david-laserscanner.com/wiki/david3_user_manual/upgrade_2_to_3
To purchase your upgrade, please contact your local reseller or visit our shop: http://www.david-laserscanner.com/?section=Buy
*Structured Light Scanning*
Structured Light (SL) makes scanning faster and easier! For this method you can use a standard video projector instead of the line laser.
This animation demonstrates the setup:
The video projector is connected to the PC and DAVID 3 uses it to illuminate the object with several stripe patterns. Click "Start" - wait a few seconds - see 3D result on screen!
Our Mexican reseller VISI Series has already tried it and made a short demo video (thank you!):
Of course an SL setup needs to be optimized and calibrated (first the camera, then the laser). Our DAVID 3 user manual will guide you through it: http://www.david-laserscanner.com/wiki/david3_user_manual/overview
So what are the pros and cons of Structured Light Scanning compared to Laser Scanning:
+ Scanning without calibration panels in the background! (Panels are only initially required for camera and projector calibration.)
+ Much faster
+ One-click scan
+ No moving parts / no influence of hand tremors etc.
+ Can use photo camera, e.g. DSLR (still not recommended, but will be great and comfortable with a future DAVID version - work in progress)
- Projector prices are dropping, but they are still more expensive than lasers
- Room needs to be rather dark, usually darker than required for laser
- Not suitable for very small details on small objects because projectors usually can't be focused to very short distances
You should definitely give it a try!
*How to Print Your Scans in 3D*
Have you ever thought about printing your scans into a solid sculpture/model? As you probably know, 3D printers exist but are still quite expensive...
Therefore we would like to recommend the 3D printing services of our two partners:
All In 3D: http://www.all-in-3d.de/allin3d_en.html
*New Products: Blue Handheld Laser, Batteries for All Handheld Lasers*
Since blue light has a very short wavelength, blue line laser can focus their light even thinner than green ones. That is great for scanning small objects when you really need to capture the finest surface details.
In addition to our wired blue laser modules, we now offer the brand new LE405-5-3-F-S(22x100):
It is battery operated and thus more flexible and easier to handle. We recommend that you use it together with our monochrome CCD camera:
Many of our customers have been asking for spare batteries for our lasers. We have now added that battery type to our shop, so you don't need to waste any more time finding a supplier.
*New Contact Page with World Map*
Although our colored world map may give the impression: We are NOT seeking world domination.
In fact the map on our new Contact Page gives you a quick overview and access to distributors in your country. Just click on your country in the map or select it from the drop down menu below.
Or would you like to get in touch with the DAVID company directly? Our contact details are just below the map.
