基于MATLAB的字符识别及其在化探野外资料整理中的应用

Character recognition based on MATLAB and its application in geochemical field data collation

在化探野外资料整理中,常常需要将野外手写记录表转化为电子版文档。本文以MATLAB编程语言为基础,利用其图像处理技术和光学字符识别(OCR)的方法编写字符识别程序,初步建立模板库。以化探野外一手资料整理为例,实现了野外手写记录表到电子版记录表的自动生成,大大提高了工作质量和工作效率。

In field data collation of geochemical exploration,handwritten field records often require to be converted into electronic documents.Based on MATLAB programming language,this paper used its image processing techniques and optical character recognition(OCR)method to write character recognition program,and preliminarily established a template library.Taking the collation of first⁃hand data in the field of geochemical exploration as an example,the automatic generation of electronic record form converted from handwritten records in the field was realized,which greatly improved the work quality and efficiency.
