Hello Chair nerd here.
I got tired of manually taking photos of chairs and not getting decent photogrammetry results.
Imma go ahead and dump a little experiment I did with arduino a round table, laser cut parts and some electronic stuff I had laying around.
inb4 Picrel is first test. Done with reality capture.
Cheers.

Chair bearing, 2 round tables, laser cut planetary gear and some electronics.

Stripped nikon remote, arduino uno and a relay module for the 12 v motor.

Motor is a 12v 5rpm incubator motor. Aligning the gears correctly was a bitch.

still have to refine the process to get this type of details but it's pretty decent!

Given the kind of thing you are doing, you might be able to benefit from a ML approach. I haven't tried this, but I did have some success with style transfer.

I'm new to this software if you have any tips I't ll be much appreciated.

Ok I'll check that thx.

That's pretty cool OP.
Those artifacts might be due to RealityCapture having trouble filtering out the background which is a common problem with turntable photogrammetry. You might want to try rotating the camera instead, but those small holes are going to be problematic either way I think. Maybe you could try getting your camera even closer.

Checked
Thex.Yeah Ithink I've got an early solution by prefiltering the images in psd. I'll post when I get a succeful test.

I like this. Very /diy/.
Keep building and modeling op.

does the fact that the object itself is rotating mess things up? since the photogrammetry will use the background to piece together the images.
