已经对立体摄影测量技术(Beard和Burke，1967)进行了评估，用于测量和勾画脸部轮廓。它的轮廓能力取决于受试者的皮肤表面纹理。成年人的皮肤质地很好，可以画出准确的轮廓。幼儿的轮廓不能令人满意，因为他们缺乏足够的皮肤纹理，并且只能精确地获得线性测量结果。用一对斜位曝光代替传统的正位曝光，消除了面部覆盖不完整的缺点。通过使用系统中结合的瞄准装置来将每次曝光定位到共同的基准，避免了对机械头定位的需要。
An assessment has been made of a stereophotogrammetric technique (Beard and Burke, 1967) for measuring and contouring the face. Its contouring capabilities depend on the skin surface texture of the subject. Adults have good skin texture and accurate contours can be drawn. Young children cannot be contoured satisfactorily because they lack adequate skin texture, and only linear measurements can be obtained with precision. The disadvantage of incomplete facial coverage was eliminated by using a pair of oblique exposures instead of the conventional frontal exposure. The need for mechanical head positioning was avoided by use of a sighting device incorporated in the system to orientate each exposure to a common datum.
