Looking for resources on scanning textures (self.gamedev)

Looking for good resources on scanning mostly flat textures. Tried to use a photograph of a tatami mat and had a lot of problems with the lens distortion. I don't own any professional photo equipment so I have to use my Pixel 6 camera. I have a couple of Ideas but I'm not really sure how to tackle the problem. Using a 3d scan app / photogrametry could be an option, but I have yet to find a fitting application. Another approach could be using a handheld scanner, but the surface has to be relatively flat. A brick wall for example would be problematic.

What is your folks workflow for capturing textures?

You'll want the most even and flat lighting possible, so pick an overcast day if it's outside, or use soft/diffuse lights if it's inside.

I read something about someone capturing normal maps by bringing a torch and taking pictures of their texture/material from the exact same angle (use a tripod) and lighting it from above, below, to the left, and right, and then somehow using those to make a normal map by using those pictures as colour channels to build up a normal texture. Sorry if that's really vague. It's all I can remember at the moment.

Edit: I found it. The article uses some old tools but I imagine the process is similar.
