X射线数字成像检测中缺陷的自动评判技术

在对目前缺陷自动检测系统所存在问题进行说明的基础上，研究一种通用的缺陷在线自动判定系统。并对其中的各关键技术进行了分析，包括在线系统设计及软件实现定位、定量和定性的技术．提出了基于双目视差法的射线图像缺陷立体定位技术，讨论了缺陷区域的分割、边缘检测、轮廓跟踪以及缺陷特征参数计算等技术，最后利用定位和定量分析得到数据，结合通用标准以及工件的制作工艺、扫查方式等综合判断缺陷的性质．

Automatic Judging System Based Digital Radiography for Defects

The problems of automatic defects inspection system in existence are described.Meanwhile,an all-purpose automatic on-line judging system for defects is presented.The key techniques,including on-line system design as well as implementation of location,quantitative and qualitative analysis,are analyzed.The 3D location technique based binocular parallax for defects is brought forward.The techniques of defecting region segmentation,edge detection,contour tracking as well as characteristic parameters computing are discussed.Finally,combining with currency standards,facture technics of object and scanning mode,the characters of defects are judged using the data from locating and quantitative analysis.
