Paper Abstract

An automated modeling system that represents an object body by a solid model of polyhedral approximation was developed using multi-directional image inputs. The principle of this solid model generation is based on the calculation of viewing pyramids consisting of the image boundary and the corresponding focal point. Applications to the non-contacting three-dimensional measurement of the shape of irregular and complicated object such as a doll, a fish, a spiral shell, and a lemon, to the automated mesh generation for the boundary element analysis of the lemon, to the CAD of a tillage blade, and to the shape, deformation and motion analysis of an aerodynamic tuft, a small tracer particle, and an alcohol wick flame for the flow visualization are presented. It appears to have considerable utility in bio-mechanics and various industrial applications.
