little hole

Postby hal » Wed Sep 19, 2007 1:38 pm

hi simon, yes, the problem of artifacts is linked with hole in mesh. but i assume this is natural when (my 3 image) i have big hole. in first image are present 1 or 3 little holes in final mesh: first time i lauch poisson fusion all works well, but other time different artifacts appears. bho. thanks for reply.

Hello hal,
The Trust WB-5400 has a CMOS-sensor. I don't know any CCD-Web Cam on market which has a resolution of 1280x1024 pixels.
First it seem so that martinziener had found one when he presented the Agent V2 Web Cam on Aug 21. But 5 days later and after some inspections by him he told us that it is also a CMOS.
Your mentioned frame rates are neary the same as I found with my TRUST.

Old/New Comparison

Postby hal » Sat Mar 10, 2012 2:28 pm

Hello,

In this period I'm nostalgic and sometimes, looking at the past years, I think how dirty and raw were my first scans (and how fun David gave to me :D ).
So, I've tried to re-scan again the same small object done in 2007.
This WarHammer series miniature was one of my first test about small objects.

The old hardware, used for Laserscanning, was an hand-held red laser leveler and a Webcam at 1024x768.
The new one for Structured Light is a DELL projector 1280x800 and a CCD camera at 1024x768.

... just to have a comparison after a doubled David version.

Attached the OBJ file, just to have a closer look (sorry, I reduced the mesh density drastically because forum uploading).

Hello,

the camera si the same of the color CCD that you find in the David Shop.
https://ssl.david-vision-systems.de/sho ... 05c470ad18
The only difference is that I use a 12 mm lens instead a 6 mm.
