In order to realize the automatic customizing for shoe lasts,a segment-based adaptive algorithm is proposed.After fitting the regular data clouds to NURBS curves,the standard shoe lasts are contracted or enlarged in each feature segment according to foot shapes to perform local modification.Then,an energy optimization-based method to modify the control points and the weight factors is proposed to fit the standard shoe lasts adaptively and to realize digital customizing the shoe lasts.The automatic custormizing shoe lasts are performed by the presented method,and the procedure from scanning the foot shape to establish a last 3D model takes time less than 120 s.The results show that the algorithm can meet the requirements of comfort and aesthetics,and can shorten the customizing time.
