关键字:图像识别 LABVIEW 圆形图像 Design of Round Image Recognition and Real-time Tracking System Based on LABVIEW Abstract Digital Image Procession is widely used in field of national defense, industrial and agricultural production, people’s daily life. Image recognition is an important part of image processing system, and a circle (including arc) test is one of the classic problems is in the digital image processing. The program of the design is developed to accomplish the task of recognition and tracking of round image. The image processing programs are based on LABVIEW platform, which can recognizes a round image, and complete real-time tracking of many round images. In the programs, a color image is converted into a grayscale image, and then into a binary image, after making image morphological processing, the programs will extract the geometry features of the binary image, finally finish the image recognition. According to the recognition of single round image, we can use while statement in LABVIEW platform, in this way, we can finish real-time tracking of the round image, Key Words: image recognition; LABVIEW; round image 目 录 1 虚拟仪器概述 1 3 3 3 5 5 5 6 7 7 8 LABVIEW软件简介 8 LABVIEW应用程序旳构成 8 LABVIEW旳基本模块 9 程序调试技术 9 找出语法错误 9 设置执行程序高亮 10 10 探针 10 10 11 11 12 15 16 17 20 22 本章小结 24 25 25 26 27 30 31 31 实时系统旳设计 31 本章小结 33 34 34 34 参照文献 35 附件1:界面设计 36 附件2:程序框图 37 致 謝 40
