Three-dimensional measurements of living objects may be made using various biostereometric techniques. Moire topography provides one-step contour line maps. It is a potential low-cost adjuvant to current photographic and cephalometric techniques for documentation of surface deformities. A relatively simple apparatus may be used with instant-processing film to produce immediate contour maps superimposed on the object image on the film. There is significant qualitative information highlighted by the fine resolution of the system. This immediate had data may be quantitatively analyzed by hand with ruler and/or caliper. In the future, off-line quantitative analysis may be made by computer. Geometric constraints of the system and examples of use of the technique are provided. Emphasis is placed on facial asymmetries that are difficult to analyze from plain photographs and inaccessible to data analysis from lateral cephalometric roentgenographs.
利用各种生物立体测量技术可以对活体进行三维测量。莫尔条纹地形图提供一步式等高线图。它是当前用于记录表面畸形的摄影和头影测量技术的一种潜在低成本辅助手段。一个相对简单的设备可与即时冲洗胶片一起使用，以生成叠加在胶片上物体图像上的即时等高线图。该系统的高分辨率突出显示了重要的定性信息。这些即时获得的数据可以用尺子和/或卡尺手工进行定量分析。未来，可以通过计算机进行离线定量分析。文中提供了该系统的几何约束条件及该技术的使用示例。重点在于面部不对称性，这些不对称性从普通照片很难分析，而从侧位头影测量X线片又无法进行数据分析。
