title: Telecentric photogrammetry: its development, testing, and application.
abstract: The development, testing, and application of a simple method of photogrammetry are outlined. Two phases of development are described, the first leading to the production of a frontal facial photograph with superimposed contour lines at 2 mm. intervals and the second leading to a frontal view together with right and left profile views of the patient. The choice of method used will naturally depend upon the purpose for which the clinician wishes to have a photogrammetric record of his patient. The root mean square error of the method is 0.33 mm.
