 摘  要
     隨著現(xiàn)代科學(xué)技術(shù)和現(xiàn)代工業(yè)生產(chǎn)的高速發(fā)展，對數(shù)控彎管機精度的要求越來越高，使得傳統(tǒng)的人工測量已經(jīng)不適應(yīng)甚至不滿足實際測試的需求，結(jié)合圖像處理的測量技術(shù)日益成為研究的熱點。NI推出的labview應(yīng)用軟件平臺和其生產(chǎn)的圖像采集卡兩相結(jié)合產(chǎn)生了新型測量方式，利用圖像采集卡采集圖像，對圖像作二值化、邊緣處理等操作，得到誤差較小的精準(zhǔn)圖像，傳輸?shù)接嬎銠C上，利用labview軟件實現(xiàn)彎管機彎角角度的即時測量，經(jīng)試驗研究分析，該方案有很高的可行性。
     本項目的設(shè)計研究采用強大的圖形化設(shè)計語言(G語言)labview編程。人機交互界面直觀友好，具有強大的數(shù)據(jù)可視化分析和儀器控制能力等特點。論文著重探討了采用圖像采集卡結(jié)合IMAQ Vision Build模塊進行圖形處理，然后labview實現(xiàn)彎管機角度測量系統(tǒng)的研究，對數(shù)控彎管機自動化、智能化、數(shù)控化方面的改進提高有及其重要的意義。

 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.
