Abstract
Some embodiments of the invention relate to a coordinate measuring method for detecting an object surface by means of a coordinate measuring machine, comprising a measuring head for accommodating a sensor, a guiding unit for producing a relative movement of the measuring head in relation to the object surface in at least one direction, an optical sensor for detecting the object surface, and a control unit, the object surface being optically detected by the optical sensor during the coordinate measuring method, and a data set representing a surface profile in an object profile domain being generated. The data set is filtered by simulating contact of the surface profile represented by the data set with a virtual tactile sensor, and a tactile data set is derived from the simulated contact such that the tactile data set represents a virtual tactile surface profile in a virtual sensor domain.
