Abstract
An orthogonally related target point array is provided in fixed relationship to an object. A photo detector image plane obtains images of the target points projected through a lens located a fixed distance from the image plane. Simple algebraic manipulation of image plane position coordinates of the images corresponding to the target points provides for the establishment of a vector replica of the target point array. The vector replica, in turn, is sufficient data to provide spatial information about the object including position and orientation information with full six-degrees-of-freedom.
