A close-range three-dimensional photogrammetric system developped for studying human knee bones is discussed. A stereophotographic facility of two non-metric cameras with syn-chronized shutters, a stereoplotter with digitizing capabilities and a micro-computer with appropriate software are capable of obtaining digital data all around the bones that constitute the human knee. Graphic representation of any part of the object by using digital information as well as perspective and stereoscopic representation of such desired part of the object is now routinely possible with an accuracy of less than ±0.3 mm.
