I've always thought highly of hiring or bribing messenger types
(couriers, garbage men, cabbies) to take photos -- with disposable
cameras -- of the street sign nearest each of their drop off locations,
while simultaneously carrying a breadcrumb-ing GPS unit.
If someone is intentionally photographing a street sign, I am certain
the vision algorithms to suck out the text are relatively trivial. It's
basically OCR for 1992.
So does anyone have a spare 100k to spend on this sure fire way to get
sued by the Royal Mail? ;)
