Abstract: A remote control system for automatically moving a moving object by remote control, comprising a plurality of functional units that transmit and receive information to and from each other, wherein at least a part of the plurality of functional units detects the presence or absence of an abnormality in another functional unit by using information received from another functional unit.

Abstract: A position estimation system, a position estimation method, and a program that can estimate a position of a moving body without installing an installation object on the moving body are provided. A position estimation system includes a detection unit configured to generate a first mask image, a mask area masking a moving body in an image photographed being added to the first mask image, a perspective transformation unit configured to perform perspective transformation on the first mask image, and a position calculation unit configured to correct a coordinate point of a first circumscribed rectangle set for a mask area in the first mask image using a second coordinate point of the mask area in the second mask image, which is obtained by performing perspective transformation on the first mask, to calculate a third coordinate point.
