ABSTRACT:
The invention relates to a device and a method for determination of location information of a workpiece. To enable rapid calibration of a relative position of the workpiece (1) in relation to a tool provided for processing said workpiece, it is proposed that the devicefeatures a camera for recording at least a partial area of the workpiece,first processing means for determination of geometrical parameters on the basis of the partial area recorded by the camera,a memory for a geometry model of the workpiece andsecond processing means for determining the location in-formation of the workpiece by reconciling the geometrical parameters with the geometry model, with the location information being provided for determining the position of the workpiece in relation to a tool pro-vided for processing it.
