岩石平巷

Examples

  1. 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。
