| Zusammenfassung | The evaluation of measurement instruments and processes by comparing them them to references has become a basic principle of metrology. In our paper this concept, which originally had been developed for the physical measurement process, is applied to measurement data processing. In this way the evaluation of several algorithms is possible where a mathematical proof fails or does not seem to be as adequate. We present the principle of a special reference algorithm supporting the quality estimation of an approximation method for shape measurement data. This approximation method, which uses non-orthogonal sine fuctions, runs successfully but has some theoretical deficiencies. |
