Title: Paint Masks with Brush
Post by: bestable on March 10, 2020, 10:43:25 AM
With "Strict masking" it is possible to get great results from few an very simple masks. No need to fine trace edges.

I just wish they could be created more easily, something like circular brush with adjustable size would be perfect.

P.S. I cant fathom how to use "Intelligent Paint".

It looks like it is just me and You, James. Sadly. This could have been huge timesaver.

We do a lot of building facade condition assessment, and so often photos are taken of a structure from the scaffolding built right onto it.

It would be so nice to be able to paint masks over the scaffold poles using a brush of varying diameter.

Currently i have a clunky workflow where i do this in photoshop by opening ~20 photos at a time, cycle through them painting over the scaffold poles on a new layer, saving, repeating for another 20, and finally running an action in image processor to turn the image black/white before re-importing as a mask.

It's a thankless task whether you do it in photoshop or metashape, but directly in metashape would still save a lot of steps!

I think you could align/model the project with both facade and the scaffolding unmasked. Then remove the facade from the model & get masks "From Model" and invert. That way you will mask scaffolding and keep the facade (for the most part).

In theory that works, but as the scaffolding is not the subject of the survey it is not photographed comprehensively enough to be reconstructed particularly well.

Plus it is generally out of focus anyway, assuming the building facade is in focus!
