摘　　要：本文将一种改进的OMR技术用于标准化考试中,采用与普通光学标记阅读机完全不同的技术,使用光学字符识别的方法、算法完成答题卡上标记的识别。此系统中图像识别是识别出考生填写的表示选项的“勾、×、○、●、／、/”等各种手写符号,它属于脱机手写体汉字识别。本文提出的方法具有很高的识别率。In the paper, we put forward the application of an improved OMR technology in standardization exam, differs from other system which is based on the optical mark recognition, the system adopt methods, algorithms of optical character recognition techniques to recognize the handwritten symbols on answer cards. So this systerm is to recognize all kinds of handwritten symbols written by examinee such as ＂勾、×、○、●、／、/＂, which is belongs to Off-Line Handwritten Chinese Character Recognition. The methods gain a high rate of correct identification.
