Abstract: Sensor signals from a sensor of a coordinate measuring machine or microscope describe a workpiece arranged within a space. The sensor and the space are movable relative to one another. A method of visualizing the sensor signals includes obtaining data relating to a three-dimensional scene that is stationary relative to the space. The method includes generating a two-dimensional view image of the scene. The view image has opposing edges predefined with respect to at least one of the two directions. A central region of the view image is located between the edges. The method includes, repeatedly, obtaining a two-dimensional sensor representation of the workpiece and combining the sensor representation with the view image to form a two-dimensional output image. The method includes, in response to movement between the sensor and the space, generating a new view image if the central region would extend beyond either of the edges.

Abstract: A method for software-based planning of a dimensional measurement of a measurement object includes receiving an input command for selecting at least one measurement element of the measurement object that is to be measured during the measurement. The method includes determining a selection of measurable test features of the at least one selected measurement element. Each of the test features includes a dimensionally measurable measurand of the at least one selected measurement element. The method includes determining a reduced subset of the selection of measurable test features depending on a view currently chosen on a display. The method includes visualizing the test features contained in the reduced subset by generating a graphical representation of each of the test features contained in the reduced subset on the display.
