PROBLEM TO BE SOLVED: To provide a deduction method for estimating the size of a measuring object which is arranged on a floor surface, and for deducing the position and direction of the measuring object with respect to the floor surface.SOLUTION: A plurality of markers having each different mark attached thereto are stuck on a fringe of a horizontal surface of a vertical surface of the measuring object such as, furniture, and on the floor surface on which the measuring object is arranged (step S101), and the measuring object and the floor surface are photographed a plurality of number of times from different photographic positions (step S102); and a calculation device included in a computer deduces a photographic position from which a photographed image is photographed, the size of the measuring object, and the position and direction of the measuring object to the floor surface, relative to each of a plurality of photographed images based on the size, position and direction of a marker image arranged on a domain wherein a marker is photographed in the plurality of photographed images acquired by photographing (steps S103-S105). |
