About a few issues on mesh
« on: May 21, 2018, 03:21:17 PM »
Hi,

I scanned a bust with a turntable and the result is pretty good.
I have some remaining issues I would like to understand.
I've got 271 photos and each photo gets its own mask.
I applied masks to Tie points.

1/ The chest is like a plane without any detail.
I checked with the green arrow this region that is rendered as you can see on the attached file, that's to say a little bit weird.

2/ There is absolutely nothing behind the head and I don't understand these small chunks of mesh (red arrows).

Thank you for your explanations !

Hello Nightingale,

Looks like an alignment issue.

Which settings for accuracy, tie point and key point limits you have used?

Also I can suggest to apply masks to key points, since you have masks for all the photos. Also disable adaptive camera model fitting.

Hello Alexey,

Thanks for reply.
I used the following settings:

Key Point Limit = 40,000
Tie Point Limit = 10,000

I launched a new workflow with these settings and following what you said.
That's to say :

Apply masks to key points.
Without any camera model fitting.

I got this result (screenshot).
It's good but it could be better. I mean it lacks a little bit of resolution.
How can we improve it ?

Another problem is as I export the mesh to Maya, it looks smoothed. I do not understand why.

Thanks for your help.
