A recognition model generation system of the invention includes means 18 for labeling edges and faces of an input three-dimensional shape, means 20 for generating shape restriction values, shape restriction means 22 for restricting shape recognition using generated shape restriction values, and means 24 for generating position coordinates of vertexes of a shape that can be derived by substituting the input three-dimensional shape with hexahedrons using output from the shape restriction means. The invention also provides a method for generating a recognition model a program for causing a computer to execute the method, a computer-readable medium storing the program thereon, and a structured mesh generation system.
