That's a pretty well-solved problem at this point, if you want to do it yourself. You'll want some kind of NeRF tool and a way to calculate the camera poses of the photos you took. COLMAP is the tool most people use for the latter.
I'd recommend trying Instant Neural Graphics Primitives (https://github.com/NVlabs/instant-ngp) from NVIDIA. It's a couple years old, so not state-of-the-art, but it runs on just about anything and is extremely fast.
Sweet, thank you for sharing. In my case, I need an api I can call cause i only have a mac air which is essentially worthless for development lol. Also I am bootstrapping a startup and one of the features is essentially turning rooms into 3d space. I know theres matterport 3d and some others but still looking for something simple where i could pay a couple cents per api call with x amount of images. does that make sense?
