METHOD FOR RESTORING THREE-DIMENSIONAL STRUCTURE FROM TWO-DIMENSIONAL MOVING PICTURE

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional structure restoring method which can secure the uniqueness of a solution without requiring to solve a nonlinear equation and can easily discriminate between translational motion and rotational motion and can obtain the absolute size of an object. SOLUTION: A sensor which measures the acceleration and the angular velocity is integrally attached to a camera 2 which picks up the moving picture of an still object 1, and the moving picture and data of the acceleration and the angular velocity are made synchronous and recorded, and the moving picture is so processed based on angular velocity data that the angular velocity may be 0, and the moving picture including only translational motion is obtained, and a three-dimensional structure is restored from this moving picture. The size of the object is obtained in accordance with a ratio (s) of the velocity obtained from acceleration data to the velocity on the moving picture including only translational motion.
