PROBLEM TO BE SOLVED: To provide a method for calculating three-dimensional information of an object from one piece of two-dimensional image on the object formed of line segments joined by a universal joint, and provide a method for analyzing movement of the object from series of two-dimensional images picked up by one camera. SOLUTION: The method for calculating the three-dimensional information from the two-dimensional image calculates the three-dimensional information of the line segments when picked up from the two-dimensional image, which the line segments joined by the universal joint is pick up, and length information of the line segments with one connection part position as a reference. A method for dynamically analyzing calculates an offset amount in an optical axis direction of both images from position deviation information on the images of the connection part as a reference from the two images on the three-dimensional information of the line segments of each image acquired by the above method on the basis of the two-dimensional image picked up chronologically, and corrects the three-dimensional information of the line segments to acquire position change information of each line segment.
