Orthomosaik in greyscale
« on: September 05, 2024, 06:54:55 PM »
Has anyone ever had that?
All orthomosaics come out as a grayscale image, colors say 1 channel, uint8.

All activated images are colorful, all scans with their images, which are grayscale, are deactivated.

I've tried everything for 3 hours now.....

Metascape takes the output channels from the input with the fewest channels at least for texture and vertex coloring. So you need to disable all single-channel input  (scans and black-and-white panoramas) before building texture or colorize vertices. I'm not totally sure it the same applies also for the orthomosaic... I would just duplicate the chunk and remove any source data with just 1 channel.

I've played through that again, you're absolutely right. By deactivating and activating images, I accidentally added a few grayscale scans. I didn't notice that.

Thanks for the help!

How old is your Metashape version? Looks extremely old.

See page 39 of the Change Log
https://www.agisoft.com/pdf/metashape_changelog.pdf

Dark and Light themes were added in version 1.3.0 in 2016, but the Classic theme has always been available.

I don't know when Agisoft switched the default theme to not be classic, but as soon as they did that I switched it back.

Having used the software since 2010 I already knew where everything was, and re-learning all the toolbar icons seemed like an extra job I didn't need, plus everything with the new themes seemed chunkier and took up too much screen space.

So I expect Dieter is using a recent version, but with the Classic theme applied.

Thats exactly the point.
