摘　　要：目的应用计算机辅助光学投射条纹测试技术(computer-aided projection fringe measurement,CAPFM)研制乳房三维形貌非接触性测量系统.方法基于CAPFM和软件编程技术研制乳房三维形貌非接触性测量仪,论述其基本结构和原理,并采用该系统测量塑料人体模特乳房三维形貌以检验其性能.结果采用该系统测量乳房具有以下优点:(1)非接触性三维测量过程;(2)测量速度快,采集数据仅需0 5 s,测量总耗时大约2～3 min;(3)自动化程度高,测量过程基本由计算机软件控制;(4)线性项目测量灵敏度达0.6mm,体积达1ml,完全满足临床需要;(5)测量结果可以数值、二维图形和三维数字图像形式存储和显示,生动形象并便于后续研究.结论基于CAPFM原理研制的乳房三维形貌非接触性测量系统是先进的和值得推广的.Objective To develop a system for three-dimensional (3D) non-contact measurement of breast using computer-aided projection fringe measurement (CAPFM). Methods A system of 3D non-contact breast measurement was developed based on CAPFM and used for measurement of a plastic model mimicking human breast. Results The CAPFM system was capable of non-contact 3D measurement with rapid data collection (within 0.5 s) and measurement (no longer than -3 min). This system was highly automatic, and with software-controlled measurement, the sensitivity was as high as 0.6 mm (for linear measurement) and 1 ml (for volume measurement), to well meet the clinical requirements. The measurement results could be stored and expressed in numerical values or represented in vivid 2D figures and 3D images, which facilitated subsequent studies. Conclusion The 3D non-contact breast measurement system on the basis of CAPFM can be helpful for medical assessment of the breast.
