Abstract
An arrangement for aligning a first object relative to a second object, in which a light pattern is projected from the first object onto the second object. An image of the pattern on the second object is recorded with a camera mounted on the first object. From the camera image it is possible to determine the relative position and orientation of the second object relative to the first object. In an alternate arrangement, a first light pattern is projected from the first object onto the second object, and a second light pattern is projected from the first object onto the second object, so that the second patten and the first pattern form a uniquely identifiable overlap pattern when the second object is in predetermined alignment with respect to the first object. From a camera image which has recorded the overlapping patterns, the position and orientation of the second object may be determined relative to the first object.
