Abstract
A method for operating a motion-measuring system of a machine, such as a coordinate-measuring device or a machine tool. An image-recording device arranged on a first part of the machine records at least one recorded image of a second part of the machine. The first part and the second part can be moved in relation to each other. A capturing structure, which is formed by the second part and/or which is arranged on the second part, is captured by the at least one recorded image, and, by using information about an actual appearance of the capturing structure, a speed of the relative motion of the first part and the second part is determined from differences of the at least one recorded image from the actual appearance of the capturing structure.
