FEATURE-BASED MAP BUILDING METHOD FOR MOBILE ROBOT

摘要

A method for making a shape-based map for a mobile robot is provided to extract a line, point, or circular shape by associating trajectories of distance information reflecting an effective beam width of a sensor, and update shape information by associating the previously extracted shape and the trajectory of the new distance information. The distance information for the shape is received by using sensor parts. The distance information corresponding to the same distance area is selected among the distance information. The trajectories, which are generated from two different positions, for the distance information corresponding to the same distance area are associated with each other. It is checked whether the trajectories are corresponding to a line, a point, or an arc through association, and the checked shapes are clustered. The extracted line, point, or arc shapes are associated with the trajectories for the new distance information. The shape information is updated through the association.
