A method for determining shape deviations of a real actual surface on the basis of measured vertical information of measurement points of the actual surface section is provided. Measurement points are located in a measurement-point extent section, wherein the method uses evaluation sections, which are arranged at offsets to each other and, altogether, extend over the measurement-point extent section. The method includes (a) for each measurement point of a number of measurement points of each evaluation section of the first evaluation sections, determining a maximum vertical distance that results as the greatest distance in a specified vertical direction between two measurement points, and (b) determining an evaluation-section slope, which represents a straight connecting line between an evaluation-section lowest point and an evaluation-section highest point, wherein, in a further step, the value pairs of a maximum vertical distance and of an evaluation-section slope, which value pairs are determined in a plurality of iterations for the respective evaluation sections thereof, are associated with a limit criterion.
A method for assessing a form deviation of an actual surface portion of a real actual surface from an intended surface portion on the basis of measured vertical information items, in each case from measurement points of a group of measurement points situated on the actual surface, wherein the group of measurement points is situated in a measurement point portion of extent, defining the positions thereof, of the actual surface portion, wherein the method uses at least one iteration, in each case with an arrangement of assessment portions, which are distributed in the actual surface portion over the measurement point portion of extent, at least on a portion-by-portion basis, and which are situated offset from one another, wherein an iteration in each case includes the following:
A computer program product comprising non-transitory computer executable program code for assessing a form deviation of an actual surface portion of a real actual surface from an intended surface portion on the basis of measured vertical information items, in each case from measurement points of a group of measurement points situated on the actual surface, wherein the group of measurement points is situated in a measurement point portion of extent, defining the positions thereof, of the actual surface portion, wherein the method uses at least one iteration, in each case with an arrangement of assessment portions, which are distributed in the actual surface portion over the measurement point portion of extent, at least on a portion-by-portion basis, and which are situated offset from one another, wherein an iteration in each case includes the following:
A surface assessment system for assessing a form deviation of an actual surface portion of a real actual surface from an intended surface portion, the surface assessment system comprising:
