Abstract
Provided are a control device, a control method, and a mobile object that enable distinction among positions and accurate estimation of a self-position even in an environment where different positions include many similar feature amounts in surroundings and are thus likely to be erroneously detected as being the same position. In accordance with a place corresponding to the self-position, an image feature amount is extracted from an image of surroundings to which a mask has been added on the basis of a place-related non-feature portion representing an area, in the image of the surroundings, that is not useful for identifying the self-position, and the image feature amount and positional information regarding the self-position are associated with each other and registered in a position/image feature amount database (DB).
