PROBLEM TO BE SOLVED: To acquire the structure of an object or accurate structure of a shape from two-dimensional(2D) measured data (measurement matrix) at a feature point provided from time sequential image data photographing the object. SOLUTION: Concerning this 3D structure acquiring method, the coordinate values of feature points constituting the structure of the object are measured in the photographed 2D image data, the feature points are time sequentially traced and concerning the provided 2D measured data of time sequential feature points, the structure or shape of the object is acquired while using a fractorizing method. In this case, the data are decomposed into action information of the camera removing a noise component and structure information of the object removing a noise component and in this decomposing process, a sensor to be operated synchronously with the physical motion of the camera measures the angle value of rotation around the horizontal axis of coordinates of the camera on a coordinate system with the viewpoint of the camera as an origin, the angle value of rotation around the vertical axis, and the angle value of rotation around an optical axis as the motion information of the camera. While using this measured motion information, the relevant motion information is corrected and the structure component of the fractorized object is restored/ reproduced.
