Abstract: A guidance system is described in which a mobile object, such as a robot, is guided along a path within a predetermined environment. It comprises first memory means to store prediction patterns of objects within the environment, second memory means to store an extraction sequence of the prediction patterns of the objects stored in said first memory means, a control device which compares for matching the prediction pattern obtained from said first and second memory means and a feature pattern obtained from an observed image, on the basis of positional information of the mobile object, and which delivers a guidance signal to the mobile object so as to diminish a difference between both the patterns when the pattern matching is possible and delivers an "mismatch" signal thereto when the matching is impossible, a display device which responds to the "pattern mismatch" signal from said control device to display this signal and to display an image of an object within the environment and the prediction pattern of an object, and input means to command said second memory means to select the prediction pattern associated with the displayed object image, on the basis of the "pattern mismatch" display of said display device.
