Human eyes are actually equivalent to very high end video cameras, and the image process that you can do in your squishy grey 10 watt processor is still way better than anything we can do with computers. You need your navigation system to be able to directly sense in 3 dimensions for it to be competitive.
Not really: we have hi dpi (and in focus) resolution only in the narrow field of view in the middle, everything else is not that good. We compensate for this by having ability to quickly move eyes and refocus.
