摘　　要：提出一种基于数学形态学定位和模糊模板匹配及垂直投影相结合的字符分割算法。先通过形态学运算得到一系列候选区域,根据先验知识从中找出封装体所在区域,再利用模糊模板匹配的方法找到字符区域,通过字符垂直投影进行单个字符分割。通过大量的实验表明,该算法能够有效解决集成电路印字定位和字符分割的问题,并具有较好的鲁棒性。An algorithm using mathematical morphology positioning and fuzzy template matching together with the vertical projection to segment the printing characters is proposed. The algorithm utilizes morphological operation to detect the candidate regions at first,finds out the package area based on a priori knowledge, uses fuzzy template matching method to find out the character area,at last uses the vertical projection algorithm to segment single character. A large number of experiments show that the algorithm can realize pesitioning and segmentation of the printing character on the integrated circuit package,and the algorithm has good robustness.
