摘要
A method for measuring a the form of a workpiece (21) in two-dimensional directions, comprising a first direction and a second direction, the essentially vertically with respect to the first direction is, comprising, in relation to the workpiece (21) comprising a form, comprising a concave shape and / or a convex form, comprising a tip portion (25) in the two-dimensional directions, the steps of:Determining a search start position, of which the search of the nose portion (25) by means of a measuring element in the first direction is started;Setting a central position;Setting a first position and a second position, in a row in the first direction are arranged, wherein the central position between them is arranged as a center, in order to have a space therebetween;Obtaining a measuring point group comprising measuring points of the central position, the first position, and the second position, wherein the measuring point a position of the measuring element is, when the measuring element on the workpiece (21); andDetermining a measurement point closest to the tip portion (25) in the measuring point group is based on positions of the measurement points in the second direction and selecting a position of the measuring point in the first direction than a selected position,wherein, when the measuring point group originally according to the determination of the search start position is obtained, the search start position than the central position is set, and if the measuring point group after the selection of the selected position is obtained, the selected position than the central position is adjusted, andthe distance in the case of each selection of the selected position is reduced, as a result of which the point group included in the measuring points are converged.
