DEVICE AND METHOD FOR DETECTING THE POSITION OF AN OBJECT IN A MACHINE TOOL

摘要

The invention relates to a device and method for detecting the position of an object in a machine tool. To this end, a camera (3) is used which supplies an image of the object (2) and of an object holder (1) to which the object is connected and the position of which within the machine tool is known. A first processing means allows the position of the object relative to the camera to be identified on the basis of geometric features of the object which are acquired from the image. A second processing means is used to identify the position of the object carrier relative to the camera on the basis of geometric features of the object holder which are acquired from the image. A third processing means finally is used to determine the relative position between the object holder and the object, which is sought, from the relative positions between the camera and the object or between the camera and the object holder.
