Ask HN: What are the laws around collecting images in the wild to build AI?

I've been wondering this for awhile now and can't find any information about it online. What are the laws (if any) put in place regarding image collection to train AI (commercial and non-commercial purposes)?

For example, let's say I wanted to train a computer vision model to recognize scenes (let's say for a real estate use case). Can I simply go to 100 restaurants, snap a photo, blur out the logo and use those images to train my model?

Can I do the same thing for electronics if I wanted to built an object recognition model?
