> I would think camera-based navigation would be fairly successful at this point. We can easily store large amounts of image and terrain data, and deep learning based image recognition systems are quite powerful.
Aside from the fact that the amount of data required for that would be orders of magnitudes larger than you can reasonably store, that wouldn't work at all in areas with little terrain features like deserts or the open sea.

- upbeat_general 5y agoIt’s certainly conceivable that you could store a compressed representation of the image features. Especially if you’re operating in a more limited environment (e.g. a large metro area), it would be very feasible to only store extracted features from the image data that you could use for matching.

Seems like technology has come quite far since then. https://en.wikipedia.org/wiki/TERCOM https://en.wikipedia.org/wiki/TERCOM Here's a modern take on it: https://www.youtube.com/watch?v=U5Kr0YI3sec https://www.youtube.com/watch?v=U5Kr0YI3sec
- Melkman 5y agoDon't look down. Look up. That's been a navigation standard for years. Funnily enough replaced by GPS. https://airandspace.si.edu/collection-objects/astro-tracker-md-1-b-52/nasm_A20110297000 https://airandspace.si.edu/collection-objects/astro-tracker-... That doesn't really work in a sub though. Also compasses (especially of the 3D variety) can be a great help.
