论文在全面阐述了光学三维轮廓位相测量术的发展、应用现状、研究热点及未来发展趋势的基础上，简要介绍了傅立叶变换和相移位相轮廓测量术的基本原理，对两种测量方法存在的问题及误差进行详细分析和比较；针对位相解包裹错误点的传播问题，作者通过改变解包裹路径来提高位相解包裹的正确性；分析讨论从解包裹位相( x ， y )到再现物体的高度h ( x ， y )物理量之间的关系，研究相应的算法，利用matlab平台，对实际采集的条纹图像进行处理和轮廓重构，其中改进及创新工作主要表现在以下两个方面： ( a )针对干涉型结构光场干涉条纹出现的漂移抖动对相移的影响，提出了一种用条纹稳定器稳定干涉条纹，用精密移动平台使物体和ccd摄像头同步移动实现等效相移的方法，建立了相应的测量系统，系统的条纹稳定可以达到。 |
