Abstract
A three-dimensional shape data production method and a system for the same for realizing contactless receiving of data regarding the inner shape of a tubular body which includes a step of generating multiple pieces of two-dimensional image data based on a signal from an image capturing device configured to be movable inside a tubular body and configured to capture an image of the inside of the tubular body; a step of receiving space information on the image capturing device upon image capturing by the image capturing device based on a signal from a motion sensor placed at the image capturing device; and a step of associating the two-dimensional image data and the space information with each other and generating three-dimensional shape data of the inside of the tubular body based on the two-dimensional image data and the space information.
