Abstract
An apparatus is disclosed comprising a base capable of receiving a camera including a lens, and a projector coupled to the base and adapted to project a plurality of beams of light onto a plane positioned at a focus distance from the base, wherein the projections of the beams of light on the plane are geometric shapes, and wherein an intersection of the geometric shapes is at the center of the field of view of the lens when the lens is installed on the base. In addition, an apparatus is disclosed comprising a base capable of receiving a camera including a lens, an image processor capable of being coupled to the camera for processing an image of a target captured by the camera, and a confirmation projector coupled to the image processor, wherein the projector projects a confirmation beam onto the plane of the target when the image processor signals the confirmation projector that it has processed the image.
