In a known method for machine-cutting a plate-shaped workpiece, position and/or geometry and/or dimensions of the workpiece are detected without contact by means of a camera and the corresponding data are subjected to an evaluation by means of image processing. Starting from this, to permit a precise and reproducible detection of the position and/or geometry and/or dimensions of the workpiece to be treated without spending a lot of time, it is suggested according to the invention that the recording of the data should comprise a method step for the coarse localization of a workpiece edge, in which the camera is operated in a first operative mode with lower optical resolution, and a second method step for determining the exact positional data of the found workpiece edge, in which the camera is operated in a second operative mode with higher optical resolution. |
