基于OpenGL的FTP三维重构

3D Reconstruction of FTP Based on OpenGL

给出了一种基于OpenGL的FTP三维重构的实现方法,解决了FTP软件实现中傅立叶变换后的频谱图、物体三维重建、三维图形显示等问题。介绍了傅立叶轮廓术的基本原理、算法的基本实现,以及测试效果。通过对光路实验采集的变形条纹图进行测试表明,该方法能够较好的快速显示FTP三维频谱图和去包裹后的三维相位图等。

This paper gives a method to realize 3D reconstruction of FTP based on OpenGL, and solves some problems such as 3D spatial frequency spectra after 2D FTF, 3D reconstruction and 3D display of object after unwrapped the phase of FTP. It introduces the basic principle of FTP, the realization of the algorithm, and the effect of the test. By testing distortion stripe images gathered from rays experiment, it could quickly and perfectly reconstruct and display 3D frequency spectra and 3D phase diagrams of FTP, etc.
