| 摘 要： | 通过LabVIEW软件平台编程实现了计算机采集莫尔条纹的图像移动来测量物体的微小位移。通过编程控制USB摄像头可采集到莫尔条纹的图像。当物体发生微小位移时,通过计算莫尔条纹移动像素点的个数,计算出物体移动的距离。本实验在测量过程中的图像采集和图像处理都是由LabVIEW软件编程来实现实时的动态自动测量。

| Abstract: | A novel dynamic measuring technique of weenie displacem ent with LabVIEW and Moire fringes is put forward in this paper.The computer gathers the image of moire fringe by USB camera.When there is weenie displacement,mode fringe will move.With the image dots of the morie,the displacement of the object can be obtained.In this experiment,gathering and managing images are processed by LabVIEW.Through these,the dynamic measurement is realized. |
