INVESTIGATION OF THE ERROR OF FILTERING OF THE SURFACE IRREGULARITIES WITH THE HELP OF A SPLINE SPATIAL FILTER

摘要

We describe the results of the algorithmic and software realization of the ISO 25178-2:2012 international standard and perform the numerical analysis of the errors of a spline space filter in comparison with the results obtained for a Gaussian space filter. The recommended parameters of the filters are determined. The algorithms and analytic software are developed in the process of investigation of the Russian standard base in the field of space 3D filtering of the surface irregularities.
