Abstract

A method for calibrating an object includes determining a position and an alignment of the object in a reference coordinate system, determining the position of at least three measurement spots by at least one capture apparatus, determining a target spot having a fixed spatial relationship with the measurement spots, determining a spatial relationship between the target spot and a tracking spot located on the object by virtue of the tracking spot being positioned at a calibration spot, and determining the spatial location of the calibration spot by a sensor.
