Abstract
The present invention relates to a map generating and updating method for mobile robot position recognition, and more specifically relates to a map generating and updating method for mobile robot position recognition, whereby position recognition error can be minimized by registering landmarks extracted during map generation and landmarks extracted on the basis of the probable error in inferred landmarks, calculating the accuracy of landmarks pre-registered during map generation, and adjusting the level of landmarks of low accuracy or removing landmarks which have been registered erroneously.
