    • A scanning electron microscope comprises an image processing system for carrying out a pattern matching between a first image and a second image. The image processing system comprises: a paint-divided image generator for generating a paint divided image based on the first image; a gravity point distribution image generator for carrying out a smoothing process of the paint divided image and generating a gravity point distribution image; an edge line segment group generation unit for generating a group of edge line segments based on the second image; a matching score calculation unit for calculating a matching score based on the gravity point distribution image and the group of edge line segments; and a maximum score position detection unit for detecting a position where the matching score becomes the maximum.
    • 扫描电子显微镜包括用于执行第一图像和第二图像之间的图案匹配的图像处理系统。 图像处理系统包括:油漆分割图像生成器,用于基于第一图像生成油漆分割图像; 重力点分布图像发生器,用于执行油漆分割图像的平滑处理并产生重力点分布图像; 边缘线段组生成单元,用于基于第二图像生成一组边缘线段; 匹配分数计算单元,用于基于重力点分布图像和边缘线段组来计算匹配分数; 以及最大得分位置检测单元,用于检测匹配得分变为最大值的位置。
