Hi there, I did to 360° scans on the turntable of this sherd 4500 BC and merged the cleaned point clouds afterwards. Lightning conditions where exactly the same, but you can tell the two scans from the colorrng. Also on some parts the surface is very smooth, on others it is kind of grainy (which I…

I see you uploaded more screenshots while I was posting my reply , I see that your merged fragments have different resolutions what will cause the difference between the sharper and smoother surface . As mentioned before it can be result because if over scanning or change in distance while scanning…

Thanks a lot, it is true that i slightly shifted distance at each scan. So i shouldn’t do that, instead turn depth and color exposure to manual. But i dindn’t lay the sherd flat on the turntable. Here you can see my setup, is it ok? [20230618_105726]

Yes , but the lighting may be better if you put your ring light being the MINI on the left side where is the RGB camera that take the pictures for color data . I see also discoloration on your object , not sure if it is light related or the color of the object [Screenshot_2023-06-18-05-31-17-266] …

Cloud Compare isn’t freeware, isn’t it? But it’s true that the sherd itself has spotted color. I’ll try it once again…

Everything starts with a proper point cloud , if it is not good , no matter what you do the mesh will never be perfect . It is hard to evaluate without actually scanning that object myself … for me looks like too much noises and shiny shading in RS5 that I personally dislike, not makes it looking …

I will do as you told in ther afternoon. In my opinion, the main problem is that the sherd is to flat. The holes in the mesh are always on the broken edges. So these edges are “underexposed”, while the bigger flat sides are maybe “overscanned”. I think i could see the mini loosing track slightly s…

Hi again, this is one single scan just as you told. Speed at 36 fps, the toggles don’t go further. Good detail, but many holes and as I tried to merge two PCs, there were seams again. The surface is also a little grainy, more than in reality. [image] Regarding color mode, you can see where th…

And afterwards i tried another setup, putting crumbled paper on the turntable. [20230619_161757] I got some nice pointclouds. Remarkable that i had to run overlap detection more than 10 times. [image] [image] But when i merged the two scans i was really disappointed: [image] Note that i m…

After many approaches: a little bit better, but not satisying entirely still. CC didn’ work properly, too.
Is this object too big for mini?
