基于视觉的表格自动识别方法

Automated Table Processing Based on Vision

表格是建筑工程图中表示信息的主要方式之一。计算机自动读图、读表技术对建筑业现代化有十分重要作用。借鉴人工读表的视觉原理和步骤,针对表格形式的多变性等特点,提出基于视觉、自顶向下的表格自动阅读方法,有效地解决了表格格式分析,识别并处理了耦合、嵌套、合并、复用等情况。

Tables in architectural drawings are one of the important means to transmit ideas of designers. Automated table processing techniques will highly improve the architectural modernization. Under the guide of the vision theory of manual process and analysis of the variable features of given tables, a from top to bottom method based on vision is proposed. This method analyzes table format efficiently,including coupling, nesting, combination and reuse of tables.
