Orage skin like surfacce

Post by Lambrescu »

Hello,
I have the following problem:
I am scanning using an HP (former David) 3D scanner, with 3D Scan Pro 5.6.0.software.
After scanning and fusing, I get an orange skin like surface (see the attached image).
Could you please help with an advice?
Many thanks

Hi,
would you mind to show the scans before fusion?
is it just a small portion of a big scan?

As a turn-around, If dimensions are not critical you could smooth it in postprocessing with GOM inspect or other free tools (it a better job than HP3D).
IMO it's not an extremely orangy scan.
I would try a better alignments and see if it helps.
Wich kind of surface is it? Ceramic?
Would you mind to share a picture of it?

At the moment I do not have a picture of the object. It is a pipe (steel).
Smoothing (in Siemens NX) do not change significantly.
Thank you

Have you covered the object with any matting compound before scanning? The scanning software can interpret the "color" difference as roughness.
P.S. I once had a similar result when scanning a dark object with sufficiently "noisy" (signal-to-noise ratio) cameras

Yes, the object was painted with a white paint, but I suspect it was not enough.
Thank you. I will o=probably rescan
