Scanning Butterflies, Moths and similar thin object areas

[dariusp]

Hello.

I'm currently using Photoscan as part of R&D for a museum, where we are scanning items in their collection. Most items are working well, usual shiny objects are causing issues but looking at using noise projection, but I am currently attempting scanning a moth.

I'm getting good alignment but the final model come out as shown in image, a big blobby mess on one wing and also in a few other places. The example image is created from the Sparse Cloud but been getting similar results with Dense Cloud.

I'm currently trying the new pre-release to see if any improvement, trying the thin dense cloud feature for example.

If anyone can share any light on what might me happening. Is it just that the wings are too thin and Photoscan is confused?

thanks in advance,

Darius
