3D Scan Forum

I've visited a local store and let them print a DIN A0 sheet for a big calibration table and will glue that to 19mm melamine-coated chipboard. The scale is ~420mm, let's see how that works out... Rangevision sounds interesting. You've said that they introduced a resolution limit for diy scanners. Is...

I'd say it's not the distance which caused these high RMS values but rather the wider view onto the panel. If i barely fit the donuts into the view, then RMS drops. If i include the whole panel (and thus the donuts become smaller) RMS increases. So your conclusion to a) use panels which are big enou...

My RMS value is more affected by the resolution of cameras (if you make a low resolution, then the result will be better on the same table) I also noticed that if the table is smaller than the area indicated in the center of the program screen, then the edges of the scan, even with a good RMS bend ...

I received a scan with a total of 32 cuts and the quality is not satisfactory. The data received in 32 cuts is about 1.8 gigabytes. Another question is what is RMS above. And where do you get that data from? Everything is unfamiliar because there is no knowledge of the camera and scan. Regarding th...

Half resolution (FullHD) - the table completely occupies the configuration area By coincidence i did it like shown in the second image. Lucky me i guess... I also haven't had issues with bend scans, however i'm using the calibration angle compensation (i got 90.3° with my plates). Here's another te...

I forgot to mention the eyes, sorry for that. The eyes on the photogrammetry scan were edited in afterwards with Meshmixer. These are glossy and transparent and thus i couldn't scan them with either technique. Besides that both scans are completely ontouched and directly out of cam (or out of scanne...

Hi all, thought i'd share the first steps with my sls rig. Setup: Viewsonic PLED-W500 (1280x800p DLP LED diamond) YW500U3M camera 5mpix USB3 YUY2 ZLKC 12mm F1.4 C-mount lens DIY 150mm panels made from cardboard and 20mm wood Total hardware costs so far: ~300€ The first calibration gave me a RMS valu...

Just tried again. T6 works, T7 doesn't (too big). 1.5mm hex is also too big. Maybe the setscrew is some imperial size? Sadly i don't have smaller hex bits to try.

The screw is either Hexagon or Torx. I think i used a T6 or T8 screwdriver. Using hex should also work.

Unscrewed another 1/2 turn (now 1.5 turns out) and here we go, perfectly sharp image at 40cm (!) distance. As you can see the distance between camera and lens is crucial to get the focus range right. Even a tiny offset will give you extremely differing results. See 2nd picture for the gap between le...
