Abstract

A control method for controlling an apparatus including a movable portion by a visual servo includes obtaining a goal image corresponding to a goal positional relationship between the movable portion and a target object, extracting goal feature points whose information has a degree of freedom of ψ from the goal image by image processing, obtaining a current image corresponding to a current positional relationship between the movable portion and the target object, extracting candidate feature points from the current image by image processing, extracting current feature points associated with the goal feature points from the candidate feature points by performing matching processing between the candidate feature points and the goal feature points, and generating, by using matching information based on matching between the current feature points and the goal feature points in the matching processing, a control signal for moving the movable portion at a degree of freedom of n.
