Abstract

An object of the present invention is to provide an autonomous moving device or the like that estimates a self position based on an arrangement of landmarks in surrounding environment while suppressing the influence by external disturbances. In order to achieve the object described above, an external disturbance factor which becomes an external disturbance and a landmark used for the self position estimation when estimating a self position from an image captured by a wide angle camera are extracted, the landmark which is not affected by the external disturbance factor is selected from an image captured by the standard camera capable of controlling a posture using the extracted information, the posture of the standard camera is controlled so as to track the selected landmark, and the self position is estimated based on the arrangement of the landmarks captured by the tracking-controlled standard camera.
