In general, the forming process of the curved hull plates consists of sub tasks, such as roll bending, line heating, and triangle heating. In order to complement the automated curved hull forming system, it is necessary to develop an algorithm to classify the curved hullplates of a ship into standard shapes with respect to the techniques of forming task, such as the roll bending, the line heating, and thetriangle heating. In the previous research, the classification algorithm of curved hull plates was studied only about rectangle shapedplates, and other limitations were notified. In this paper, the classification algorithm is extended to classify not only rectangle shapedplates but also arbitrary polygon hull plates. The discrete curvature can be computed by using arbitrary polygon mesh which isrepresented by half-edge data structure and discrete differential geometry. The algorithm tests to verify the developed algorithm withsample plates of a real ship data have been performed.
