An information processing apparatus acquires a plurality of images that is based on image capturing performed by a plurality of imaging apparatuses, acquires three-dimensional shape data of an object which is generated based on the plurality of images and states of the plurality of imaging apparatuses obtained at a time point earlier than a time point of the image capturing, detects that a state of any one of the plurality of imaging apparatuses obtained at a time point of the image capturing is different from a state thereof obtained at a time point earlier than a time point of the image capturing, based on the acquired plurality of images and the acquired three-dimensional shape data, and outputs information that is based on a result of the detection.
