Paper Abstract

This paper describes a procedure that deals with the on-line stereo measurement of multi-media images. This method is able to trace the ray from the object point to the image point through refracting surfaces between different media. The geometric paramters of the surfaces as well as the refraction indices are part of the orientation data. Hence a functional correction of the refraction effects in the image plane will be unnecessary. At first the equation describing the ray tracing are explained briefly, followed by a description of the integration of the algorithms into the Loop-program of the analytical plotter Zeiss Planicomp C100. By means of an example with plane refracting surfaces the advantages of this procedure will be shown in contrast to the solution working with functional correction in the image plane.
