Feature-based reverse engineering of mannequin for garment design

This paper discusses the issues of applying feature technology to the rever se engineering a mannequin. A torso of a person is described by a cloud of points obtained from a co-ordinate measuring device. The feature model of a mannequin consists of the major features of the torso for garment design. These features are recognized from the point cloud by comparing with a gene ric feature model. Association is set up between the point cloud and the ma nnequin features. Fitting the generic feature model to the point cloud yiel ds the mannequin feature model of a specific person. This is achieved by op timizing the distance between the point cloud and the feature surface, subj ect to the continuity requirements. The approach is useful in torso measure ment for garment panel design. (C) 1999 Elsevier Science Ltd. All rights re served.
