摘    要:本文首先对PC—BS图象测量输入系统的宝石轴承图象边界采集原理进行分析,提出了坐标重建、直角坐标修正和多边界数据分离等边界预处理方法;然后,着重讨论了用于轴承边界的圆度、尺寸和圆心度检测的两种计算方法—点—圆变换法和圆形曲线拟合法。初步实验表明,本文所提出的检测方法是正确可行的,具有一定的实用价值。

关 键 词:宝石轴承  图象边界检测

Abstract:This paper, first, analyses the image boundary sampling principle of the gem bearing in PC-BS image measure-input system, and presents the methods for image boundary preprocessing—coordinate reconstruction, Cartesian coordinates adjustment and multi-boundary division. Then, two methods are discussed which are point-circle transformation and circular curve fitting for inspecting the bearing's circularity, dimension and concentricity. The preliminary experiments show that the proposed inspection methods are correct, feasible and practical.
Keywords:gem bearing  image boundary inspection
