blurry regions in both mesh and texture

[mraw]

Hello,
we have shot this model with a crosspolarized flash-light setup. I would be pretty happy with the results, but there are strange blurry patches which I can't explain.
What I did.
- aligned photos with these settings(s. attachement)
- used gradual selection for higher certainty
- build mesh from depth maps; ultra high settings; mild filtering.

Please help. What is the reason of these patches? What can I check? What can I improve?


PS: Is there any feature in metashape where the point cloud is coloured to tell the user what area are covered good by the photos(green) and what areas not(red). Like in Reality Capture...

Hello mraw,

How does the camera alignment look like (I mean estimated camera orientation in the model view) and what values have the adjusted calibration parameters in the Camera Calibration dialog?

For me this noise on the surface looks to be related to the alignment problems and I would suggest to re-align the cameras using High accuracy and with adaptive camera model fitting disabled. Also you can build mesh using High quality option.

You can switch to the model confidence view mode in the Model view to see "good" and "bad" mesh parts.

Hello Alexey,
thank you so much for coming back to you. Thanks for the 'confidence view'- I overlooked that.
I'll attach screenshots for this, camera alignment in viewport and the camera calibr dialog.
thank you

the 'patches' seen in the results- is the reason we haved used 2 different focal lenghts?
