You start by turning your expectations down massively. Then you either download Meshroom or skip it directly to pirating 3DF Zephyr and feed bunch of photos into it, and then Wait.

Echoing this.
Photogrammetry is difficult to get right.harsh lighting helps.
Add dot stickers to shit that has little contrast and expect to do a lot of tidying up.

Just know meshroom is slow and shit and you should use pretty much anything else.

It's the Blender issue. The fact that it's free is what makes it useable.

I tried photogrametry.
It is shit.

>b-b-b-b muh photos
Get a 3D scanner the AI shit will not work.
Pro tip ! Good 3D scanners costs an arm and a leg !

Question on this.
I'm trying to model a vehicle. I have no access to it irl, so only pictures on the internet for me, but the catch is the pictures are all decades old garbage.

Can I paint the sides of the vehicle using 'pure hue/vibrant' colors and throw it in meshroom? Will it be able to resolve the overall dimensions this way? I mean, like pictures of a cube, if I paint the sides red/green/blue/yellow/cyan/magenta.

Get a proper camera+lens, preferably something prosumer.

That’s a cool pic

I'm having trouble with a symmetrical-enough object: Metashape is putting all cameras on a single side. How to deal with this?

You need high quality source images for photogrammetry, if you're planning on doing a vehicle you don't have access to that kind of thing you're way better off just using those pictures as reference and modeling it the old-school way with some photo matching.

Yeah, I was modelling it the old way.
But also I just managed to find a guy that recorded a decent enough video of the vehicle, threw it in the software and got a good mesh to compare my model to (which was the goal).
My model is off a little bit, but now I'm going to correct it.

read about bundle adjustment
if you are trying to register rigid things, orthogonal procrustes analysis can be helpful

Nice. You should take a picture.
