PROBLEM TO BE SOLVED: To provide a method for mapping an object mesh model on a three-dimensional curved surface to enable a three-dimensional object mesh model to be mapped on a certain three-dimensional curved surface based on competitive learning. SOLUTION: The mapping method is for mapping a three-dimensional object mesh model on an object curved surface, i.e., a mapped surface, based on competitive learning. The object curved surface is a certain three-dimensional curved surface comprising a plurality of control points. The three-dimensional object mesh model is a triangular mesh model (hereinafter simply referred to as SDM) capable of shape deformation. The mapping method has a first step for moving the apexes of the SDM according to the control point of the object curved surface while adopting the techniques of competitive learning, so as to deform the shape of the SDM and restore the shape of the object curved surface, and a second step for defining an energy function aimed at the shape restoration of the object curved surface, and minimizing the energy function defined so as to further deform the shape of the SDM and achieve the shape restoration of the object curved surface with higher accuracy.
