A target plane in fixed relationship to an object provides a first triad of three collinear target points which lie on a first line projection and a second triad of target points which lie on a second line projection which is in nonalignment with the first triad. A photo detector image plane obtains images of the target points projected on the image plane 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 vector replicas of the position of the target points. The vector replicas, in turn, are sufficient data to provide spatial information about the object including position and oriention information with full six-degrees-of-freedom.
