1. An optical projection system comprising: an image-projecting device for projecting an image onto an object; a target-locating device for determining misalignment of at least one target relative to corresponding target projections projected by the image-projecting device to determine the orientation of the image-projecting device relative to the object, wherein the at least one target is in mechanical communication with the object; and an image-rendering device for rendering the image projected by the image-projecting device based upon the determined orientation of the image-projecting device relative to the object.
