摘　　要：为了在生产过程中实现对被测工件尺寸和其它参数精确、快速和可靠测量,设计了一种嵌入式二维图像测量系统；介绍了其硬件电路原理及实现、二维图像测量原理、图像处理算法和应用程序开发；对系统电路的重要单元模块进行了详细的分析和阐述；实验测试表明系统工作正常,测量精度可达0．07mm,适合塑钢门窗等PVC异型材检测的工业现场应用。For precise and real--time measurement of workpiece＇s size and other parameters in manufacturing process, an embedded 2--D image measuring system is designed. The system hardware design, 2--D image measuring theory, image processing algorithm and software development are introduced. Important function units of the system circuit are described and expounded. The test result indicates that the system works normally and the precision could achieve 0. 07mm. It is suitable for application in the manufacture of PVC （polyvinyl chloride） doors and windows.
