Many potential customers ask about how we can make color textures with a monochrome camera, and what the quality is. The last results are >1 year old, so today I have made another quick demo scan including nice scan quality.
I don't have an SLS-2 available, so I used my SLS-1. Result should be about the same. You can download the scan here:http://downloads.david-3d.com/scans/Col ... e-Demo.zip
This photo shows what I did: I put a green Yoda plus a blue medicine box with red text on my brown wooden table and scanned that (one single scan only). Usually you would use a black table/background to avoid scanning it.
The result .OBJ can be imported in our DAVID software (Free Edition), Shapefusion menu, "+" button:http://www.david-3d.com/?section=Downloads
The other files, .MTL and .PNG, must be in the same folder.
In DAVID, you can use the Visibility buttons to toggle the texture on and off. Or keyboard T.
The texture coordinates are very precise because it's trivial for us to compute them: We use the same camera for 3D points and texture colors, so it's the same pixels. Each pixel = one 3D point. Each pixel = one color.About this scan:
DAVID 3.9, Original scan, no post-processing. No smoothing. Setting "Quality". Scan time 10 seconds including texture, scanned area around 150*110mm. Scanner distance around 280 mm.Result quality:
When you switch off the texture, you can clearly see small details like Yoda's wrinkles and the Braille on the box.
With texture, you can see that the colors are like a usual color photo from a color camera.Result limitations:
There are gaps in the Yoda figure because it's only one scan from one direction. You would make more scans around the object and combine them in the DAVID software to get 360°. Gaps can also be interpolated.
There are gaps on the medicine box where there is text written on it. At the border of the letters, often small deviations occur which we can't correct (optical reasons). Therefore the DAVID software automatically removes those problematic data (filter settings "Quality Check"). Those gaps would be automatically interpolated in the final processing step, Fusion.
You can find some 360° degree scan results in the Examples section on our website: http://www.david-3d.com/?section=Downloads
Some including color texture.
Also you will find a lot of results in this forum, made by various people.
