Device and method for detecting the position of an object in a machine tool

A device for detecting the position of an object in a machine tool, the device comprising:

• a camera configured to provide an image of the object;
• an object carrier to which the object is connected and whose position within the machine tool is known;
• a first processing unit configured to identify a position of the object relative to the camera based on geometric features of the object which are obtained from the image;
• a second processing unit configured to identify a position of the object carrier relative to the camera based on geometric features of the object carrier which are obtained from the image;
• and
• a third processing unit configured to determine a position of the object relative to the object carrier from the identified positions of the object and the object carrier relative to the camera.

A method for detecting the position of an object in a machine tool, the method comprising:

• capturing, using a camera, an image of the object and an object carrier to which the object is connected and whose position within the machine tool is known;
• determining a position of the object relative to the camera based on geometric features of the object obtained from the image;
• determining a position of the object carrier relative to the camera based on geometric features of the object carrier obtained from the image;
• and
• determining a position of the object relative to the object carrier from the determined positions of the object and the object carrier relative to the camera.
