Method for self-localization of robot based on object recognition and environment information around recognized object

摘要

A method for self-localization of a robot, the robot including a camera unit, a database storing a map around a robot traveling path, and a position arithmetic unit estimating the position of the robot, includes: acquiring an image around the robot, in the camera unit. Further, the method includes recognizing, in the position arithmetic unit, an individual object in the image acquired by the camera unit, to generate position values on a camera coordinate system of local feature points of the individual objects and local feature points of a surrounding environment including the individual objects; and estimating, in the position arithmetic unit, the position of the robot on the basis of the map and the position values on the camera coordinate system of local feature points of the individual objects and local feature points of a surrounding environment including the individual objects.
