 摘  要
     随着现代科学技术和现代工业生产的高速发展，对数控弯管机精度的要求越来越高，使得传统的人工测量已经不适应甚至不满足实际测试的需求，结合图像处理的测量技术日益成为研究的热点。NI推出的labview应用软件平台和其生产的图像采集卡两相结合产生了新型测量方式，利用图像采集卡采集图像，对图像作二值化、边缘处理等操作，得到误差较小的精准图像，传输到计算机上，利用labview软件实现弯管机弯角角度的即时测量，经试验研究分析，该方案有很高的可行性。
     本项目的设计研究采用强大的图形化设计语言(G语言)labview编程。人机交互界面直观友好，具有强大的数据可视化分析和仪器控制能力等特点。文档着重探讨了采用图像采集卡结合IMAQ Vision Build模块进行图形处理，然后labview实现弯管机角度测量系统的研究，对数控弯管机自动化、智能化、数控化方面的改进提高有及其重要的意义。

 Abstract
 With the development of modern science and technology and modern industrial production, the CNC Bending meet the increasingly demanding with   high-precision, making the traditional manual measurement has not adapted or does not meet the actual demand for testing. NI’s application software platform
of labview and its production of the image acquisition card combining the two have a different measurement methods, the use of image acquisition card collecting images, the images of the two values, edge processing mode of operation, received a smaller error Precision images, transmitted to the computer, using labview software Bending corners angle measurement，through the research and study,we know the programme has a high possibility.
       In this paper, the project design of using a powerful graphical design language (G language) labview programming. HCI has friendly and intuitive interface and a powerful visual data analysis and control equipment, and other characteristics. Papers focused on the use of image acquisition card with IMAQ Vision Build to a graphics processing module, and then labview achieve Bending angle measurement system of the NC Bending automation, intelligent, and the improvement of NC and its importance has increased Significance.

Keywords:  image acquisition card, labview, image processing, IMAQVision Module
