Fourier-Transform Profilometry (FTP) 是一种非接触式表面测量技术,它使用干涉仪来测量物体表面的微小变化。在MATLAB中,我们可以通过编写算法和工具来实现FTP。 首先,我们需要创建一个函数来计算物体表面的振幅分布。这个函数需要输入干涉图的原始数据,然后通过傅里叶变换将数据从时域转换到频域。接着,我们需要计算物体...
In the method of Fourier transform profilometry( FTP),the measurement system obtains the deformation of the object height modulated light field by the imaging device,and restores the height information of the object through the Fourier transform,frequency domain filtering and Fourier inverse transformatio...
On the basis of Fourier transform profilometry, we design interactive simulation interface of Fourier transform profilometry (FTP) with MATLAB GUI, then we can get the simulation results of three-dimensional shape measurement. The platform has the advantages of friendly man-machine interface, convenient...
