TH66724B - Method for obtaining eyeglass rim border combinations - Google Patents

Abstract

DC60 Method for determining rim boundary datasets consists of the following steps: a) obtaining multiple 3D measured points (N) along the rim boundaries; b) Calculating a good torus. c) Selection of point T between measured points N deviating from one of the torus at Best than Default d) Creating a border data set with three-dimensional (NT) measured points, where the selected point T of step c) is excluded from the list of three-dimensionally measured points of the step a)
