METHOD FOR ALIGNING AN OBJECT

摘要

The invention relates a method for aligning an object by rotating the same about at least one rotation axis, wherein a marker is detected by way of a camera and is imaged as a marker image, and either the camera takes part in the rotation and the marker is fixed in a direction, or vice versa, such that a relative rotation occurs between the marker and the camera upon the rotation of the object. The actual orientation, which is present between the camera and the marker before the rotation, is derived by means of image processing either from the orientation having the marker image in the field of view of the camera prior to the rotation, or from the linear extension the marker image has in the field of view of the camera prior to the rotation, and the result is used in order to determine a target rotation angle, about which the object is to be rotated about the rotation axis for the alignment thereof in a certain target direction. Subsequently, the object is rotated by the target rotation angle about the rotation axis, and thus aligned in the target direction.
