I wonder how long it's going to be before we're able to run a significant portion of Youtube video (tourist videos, etc) through something like this, and generate a huge 3d mesh of the world. Combined with Street View data, you'd really have a ton of spaces covered.

I believe random videos are too low of a quality. Like this, most of the stuff I've seen uses constrained videos.

I have seen random still images used for this kind of thing: https://nerf-w.github.io/

I haven't heard of any equivalent of EXIF for video. That goes a long way when trying to make sense of random video both for camera settings as well as GPS location if you're trying to correlate multiple videos.

GoPro has a proprietary format that stores live metadata in the videos if I recall. Maybe it’s called GPX? About 6 months ago I extracted GPS coordinates from a video using an open source tool.

Google will do this, and then sell the data to security institutions. We will be told about it later, or consent to it during a Terms&Conditions update.

Cool idea, but how would you keep it maintained? It's tricky enough to keep maps up to date. A 3D Mesh would be even more complex to maintain.
