Abstract:

Aiming at the problems of the feature-based parameter human modeling method on diformation precision and personalization representation, based on the analysis of the characteristics of the guman body part modeling and deformation, this paper proposes a novel parameterization human modiling and deformation algorithm. At first the characteristic waist contour of the mannequin model is obtained by the cross cutting of the horizontal cross sections, then the characteristic dimension parameters of human body are introduced and 3 iteration initial axles and initial values on the front, back and lateral faces on the waist contour are deermined; then the point coordinates of the waist contour are calculated by applying the weighted average of the included angles, and the deformation of the waist contour is realized. Finally, the iteration initial values of the contours are acquired in the specified deformation area according to the heights of other contours and the initial values of the initial values of the waist contour, and the deformation of other contours in the specified deformation area is realized to complete the whole deformation of the area. A personalized human body model is obtained from the digital mannequin model by deforming based on the specified characteristic values.
