例句与用法

1. 3 ) for weak noise interferogram or filtered interferogram , dyadic wavelet can be used to detect fringe edges . a gvf snake model was used to link discrete edges , the linked edges were kept well accordance with fringes of phase map . 4 ) phase unwrapping algorithm based on edge detection is suitable to well separated fringes , the unwrapped phase can be rewrapped to the original phase map
   4 ）对于低噪声情况下或滤波后的干涉条纹图，在基于边缘检测的相位解缠过程中，利用snake模型可以高效准确的实现边缘点的连接，所连接的边缘线与干涉条纹很好的吻合，可将连线的精度控制在三个像元。
2. Secondly , in phase unwrapping to overcome the spread of wrong point , changing the patch of unwrapping phase is done to improve the correctness of it . then , the relation between the unwrapping phase and the height of reconstructed object is discussed detailedly . the data processing , algorithm analysis and reconstructing object are done for the collecting fringe image which are all based on matlab language , in all these achievements , the improvement and innovation aspect are following : a ) in order to stabilize the interference fringe , a new equivalent shifting object method is presented by using fringe stabilizing device to stabilize the interference fringe though moving object and ccd camera which fixed on a precise moving platform together , the experimental result shows the fringe drift is less than a / 20 in five minutes , and the equivalent phase shifting precision is x / 100
   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。
