How to Improve Roof Surface Texture

[kikbak]

Hello,

The attached picture shows a roof with much distortion in the output orthoimage.  Is there a way to improve this detail?  The rest of the image (primarily ground features) appears good.

Thank you

post screenshot of  pure mesh = you have not a clean ( no noise) surface = problems with texture...

I'm certain this is because of shiny metallic roof but have no idea how this could be remedied.  Will the point cloud or mesh need to be edited elsewhere?  thanks

If you have Photoshop you could try batch pre-processing the images by applying image -> shadows/highlights correction (reduce highlights to reduce shininess of the roof). Then put the edited images through PhotoScan, might help the software find better matches despite the shiny surface.

I can suggest to vary the depth filtering mode for the Dense Cloud generation.

If it doesn't help in principle it is possible to manually remove dense cloud points generated in the wrong positions (not on the roof, but somewhere "inside" the house) and then generate mesh with Extrapolation, thus filling the holes.

Thank you for these great suggestions.  I will experiment to see what works the best.  Thanks again!

If all else fails you can try smoothing the roof geometry in other 3D apps.  Zbrush would be ideal but even free blender has sculpt tools.  Try use adaptive or standard ortophoto for UV so you get a editable UV.  Bring the UV in to photoshop and clone stamp the roof.  Looks like it has a regular pattern so should be a 10 min job to fix it up in photoshop.
