| 摘 要： | 提出了基于工业CT技术的装配缺陷自动检测系统的设计方法。系统采用C／S模式，以C＋＋Builder作为前端开发工具，以SQL Server2000作为后台数据库管理系统，可实现工件内部的漏装和误装等装配缺陷无损检测。利用重建图像的灰度级数快速定位出粗略缺陷区域，再以圆投影值、方向码值、Zernike矩值作为特征参数对缺陷精确识别。系统已在重庆大学ICT中心投入使用，识别速度和精度均达到用户要求，运行效果良好。

| Abstract: | A design method of automatic assembly defect detecting system based on industrial computer tomography technology was referred.For the realization of non-destructive detecting of assembly defects such as leak installing and wrongly installing in work piece internal structure,this system adopted C/S model,using C++ Builder as front-end development tool and using SQL Server 2000 as background database management system.First defect region was located fast and coarsely using gray levels of the reconstructed ima... |
