A localization method of moving robot

A method of recognizing a position of a movable robot is provided to exactly determining a position of a movable robot regardless of various errors by correcting a heading angle of the movable robot several times until the movable robot reaches a predetermined node. A method of recognizing a position of a movable robot comprises the steps of taking a photograph of an omnidirectional image by a movable robot(40) and checking at least one node at which an omnidirectional image having high correlation with the omnidirectional image is photographed(44). If it is determined that the movable robot reaches a first node, at which an omnidirectional image having the highest correlation with the omnidirectional image is photographed, it is recognized that the movable robot reaches the first node. If a correlation coefficient between the omnidirectional image at the first node and the photographed omnidirectional image is larger than a reference value, it is determined that the movable robot reaches the first node.
