Abstract

This paper proposes a method of estimation of the anatomical landmarks that are needed in product design from point clouds of body shape measured by a three-dimensional scanner. The algorithm is described briefly. First, the standard model is defined as the average shape with anatomical landmarks calculated from multiple body data samples with given anatomical landmarks. Then, the matching transformation is applied to the standard model so that it fits the body shape data of the target model. The anatomical landmarks of the target body shape are estimated from the deformed standard model. Free-form deformation (FFD) is used as the matching transformation, in which the deformation control lattice coordinates are determined from an estimation formula derived by multiple regression analysis of the multiple body data sample. This method is applied to a foot model for shoe design. The effectiveness of the proposed method is verified by an experimental evaluation. © 2005 Wiley Periodicals, Inc.
