Paper Abstract

A method for the transformation of irregularly distributed data points into a regular grid is presented. In this transformation local approximations of surface patches are used. In order to avoid undesired clipping of the surface area at the margins, a particular criterion discarding unreliable surface patches is applied. As an application, a transformation of rasterstereographic data from a back shape measurement is presented. Approximation theory shows that in the special application of back surface measurement a high accuracy can be acnieved.
