Abstract :
The authors present a visual method which allows an automated guided vehicle to recover its absolute position anywhere on a guide-path represented by a pseudorandom binary sequence whose terms are marked as distinct graphical symbols. An onboard image-processing system recognizes these symbols and finally recovers the pseudorandom code identifying the position
