Office photogrammetry usecase problems

Hi,

Ive been using Capturing reality with great outcome recently.

I wanted to do a reconstruction of an office meeting room for a client recently and i was unable to obtain good results. I know that plain white walls and plastic tables are not good for photogrammetry but i didnt expect to have such poor results… (see attached file) I took 200 photos of this small space. Even the plastic white chair dont reconstruct properly.

Is there best practices for plain white wall reconstruction and plain objects ? (i know as a last resort I could print some markers and put them on the walls but thats very long and that needs post work too…)

Would that problems be solved if i had several scans of that same space ?

And lastly how can I reset all my settings to the default ones ?

Thanks a lot.

Please help !

looks like a hard scene.

i would try processing photos differently. you may need to try a few different things.

i guess you would need to try and get as much texture/variation on the white chairs.

though i would probably have a go at very flat photos, then adding a mirco contrast like clarity in lightroom.

or going higher contrast photos, though you don’t really want to blow out any the highlights.

I think it will require experimentation

Hi henri
Can you send me the original RAW files used for reconstruction ? As has Chris mentioned, white “featureless” subject are problematic to reconstruct in general… So it needs a proper planning on data capture…

Hi wishgranter,
Could you suggest how to go about shooting in such difficult situations? Thanks

Hi raghav
Properly shot for photogrammetry, LOT of overlap, alternatively shoot with some projections for the walls. But remember photogrammetry has some limitations and white/dark, featureless stuff is always a problem… The best solution is to have this laser-scanned and use images for texturing only…

Hi, I just love the way you decor the home office. I will surely follow it. I have just shifted to Sydney, Australia and looking to buy furniture and lighting for home office like desk and chairs. Thanks for images for taking idea!

Hi, I was wondering what affordable scanner would you recommend for an enthusiast who wants to recreate personal cottages or homes?

I am currently on a monthly subscription through steam but would like to see how I could use laser scanning for interiors.

I mean I could redo everything in blender or modo and retexture the images… But was hoping to understand a good laser solution.

Thx!

Just my 10 cents:

For the way the images are taken (more or less all in one plane above the ground = chin height) I think that the result is not bad at all! Especially since the colours are a nightmare (black AND shiny table)!
So I think you can be pleased with what you accomplished in the first go.
