摘要
针对传统的激光散斑图像位移测量系统存在测量误差较大、测量时间较长等问题,设计了一种基于相位分析的激光散斑图像位移测量系统。通过激光散斑测量系统原理以及被测物的特性,构建基于相位分析的激光散斑图像位移测量系统。分别研究了激光散斑图像处理的关键技术以及适用范围。在基于Matlab平台的基础上,将图像采集库与图像库相结合,引用C++语言构建相应的激光散斑图像位移测量软件,实现基于相位分析的激光散斑图像位移测量。实验结果表明,本文系统能够快速、准确进行激光散斑图像位移测量。
Aiming at the problems of traditional laser speckle image displacement measurement system with large measurement error and long measurement time,a laser speckle image displacement measurement system based on phase analysis is designed. Based on the principle of laser speckle measurement system and the characteristics of the measured object,a laser speckle image displacement measurement system based on phase analysis is constructed. The key technologies and application range of laser speckle image processing are studied separately. Based on the Matlab platform,the image acquisition library and image library are combined,and the corresponding laser speckle image displacement measurement software is constructed by C++ language to realize the laser speckle image displacement measurement based on phase analysis. The experimental results show that the designed system can quickly and accurately measure the displacement of laser speckle images.
