Since you're going to have a vision platform, why not use it for actual
ded-reckoning [sic]? (Pedantic Note:  That's not a typo.  The "ded" is
short for "deductive." Ded-reckoning is navigation by reference to known
landmarks, or so I was taught in ground school).

There are some spectacular pattern recognition systems available off the
shelf these days.  Why not have your robot look around to see where it is?
