Abstract: A geometric structure analyzing method, a geometric structure analyzing system, and a computer program product are provided, to analyze a two-dimensional geometric structure of a model composed of at least one magnetic building block. A magnetic field intensity image of the model is obtained, and a shape of the magnetic field intensity image is used as a contour of the model. The contour of the model is skeletonized to obtain the two-dimensional geometric structure of the model, and the two-dimensional geometric structure is displayed on a display panel. Therefore, a user is allowed to control the two-dimensional geometric structure on the display panel by manipulating the model, to achieve interactive effects including visual and tactile feedbacks.

Abstract: The present invention provides an identification system and an identification method for a shielded magnetic unit. A shielding element is disposed at periphery of a magnet in a shield of a magnetic unit, such that the magnetic line of the magnet is directed back inside the shield. Moreover, after the identification system for a magnetic unit obtains a data curve to be identified of the shield, the data curve to be identified of the shield can be compared with a plurality of sets of characteristic data curves, so as to define an identification code of the magnetic unit. Accordingly, the present invention can solve the problem of interference and difficult identification while simultaneously detecting a plurality of magnetic units.
