A method and apparatus for the quantitative measurement of the accuracy of surface area

摘要

A method for the quantitative Measurement of the precision parameters of the surface of an area.Understanding: a Flat, Monochromatic Light Wave Guide Towards a predefined surface area; recording an image of the reflected light with a camera and a Lens System that focused onSurface area; deduce The Precision parameters of the surface from the recorded Image; characterized by these parameters of Surface Accuracy of the Determining of the ifFollows: obtained a two-dimensional Spatial Spectrum (Sikh (U,(V) The Geometry of the surface by a Fourier transformation of the recorded Image; adjust the default components of Fourier (Aprilia A2P A3P,,,A4p) in a major Axis Cut along the Axis of maximum elongation Of An elliptical Gaussian Distribution noise (S3) of the two-dimensional Spatial Spectrum (Sikh (U,V); adjust the Fourier Components (A1M, A2M, defaultA3M) in a minor Axis off Axis through the Lesser elongation of the Elliptical Gaussian Distribution noise Spectrum (S3) in the two-dimensional Space (Sikh (U,V); determine the precision parameters of the surface of the surface area from those Fourier components.
