三维面形测量技术的新进展

New Progress in 3 D Shape Measurement Technology *

三维面形测量（即三维物体表面轮廓测量）是获取物体形态特征的一种重要手段，也是记录、比较、复制物体形态特征的基础．三维面形测量技术在机器视觉、自动加工、工业检测、产品质量控制、实物仿形。

Three dimensional (3 D) shape measurement, i.e. surface topography measurement of 3 D objects, is becoming a powerful tool for obtaining the form and structure of objects. It is also the basis for recording, comparing and copying the shape of objects and has important significance and widespread application in machine vision, automatic manufacturing, industrial inspection, quality control, solid modeling, biomedicine, etc.
