PROBLEM TO BE SOLVED: To adapt a low rank matrix to a matrix provided with a defective element by applying repetition algorithm to three minimum components, improving the construction and estimation of a third matrix, decomposing the third matrix and obtaining a complete scene structure. SOLUTION: A device 800 is provided with a camera 820 for obtaining the image sequence of a fixed scene 810 and further, a confirmation/tracking means 830 for confirming/tracking a point origin through a sequence is provided. Then, the calculation means 840 of the device 800 constructs a first matrix composed of a point position from a motion sequence, constructs the first matrix provided with a part of the defective elements by using the coordinate of an origin for which a part of the origins are not present in a part of images, selects the triple of columns from the first matrix, obtains a second matrix from the zero space, obtains the three minimum components of the second matrix, applies the repetition algorithm to the three minimum components, improves the construction and estimation of the third matrix, decomposes the third matrix, obtains the complete scene structure and constructs an approximate solution. |
