Abstract

Only the two-viewing-planes-projection measuring principle is able to measure each closed spectacle frame. It is the first functional optical principle for this measuring task. All the other frame tracers on the market depend on a tactile measuring principle. They are especially not able to measure the needed ground of the groove in the frame of so called high curved sport frames. Therefore, till now, a two-dimensional measurement of a pattern plane was used instead of measuring the three-dimensional groove.<br />The two-viewing-planes-projection setup can calculate out of two 90° shifted perspectives of the spectacle frame by a camera system the form and the circumference for the needed eyeglasses – even for sport frames.
