表格文档在日常生活中运用十分广泛 ,它应用于人口普查、银行票据、各类报表等领域 ,对这类文档进行计算机自动处理具有重要的现实意义。表格文档信息处理系统主要由文档原始图像获取、文档结构提取和填写信息识别等部分组成。在分析了国内外表格文档信息自动录入系统的优缺点后 ,采用一种基于接触式图像传感器 (CIS)摄取表格文档的原始图像信号 ,利用硬件获得了高质量的图像信号。采用光学字符识别 (OCR)技术对填写的表格文档信息进行识别。该表格文档信息处理系统具有对表格文档的纸张和填写的要求低和识别准确度高的特点。
Form documents are widely used in daily life. They are used in censuses, bank bills, various reports and other fields. It is of great practical significance to computer-process such documents automatically. Form document information processing system is mainly obtained by the original image of the document, the document structure to extract and fill in the information identification and other components. After analyzing the merits and demerits of automatic document entry system of form document at home and abroad, a high quality image signal was obtained by using a raw image signal based on contact image sensor (CIS) ingestion form document. The optical character recognition (OCR) technology to fill in the form of document information to identify. This form document information processing system has the characteristics of low requirements for paper and filling of form documents and high recognition accuracy.
