摘要： 结合某铁路分局车辆段列车轮轴卡片自动录入及管理系统开发的实际，提出了一种单色表格的快速分析方法。其主要内容是：利用Radon变换检测表格的歪斜角度将其校正，用投影法找出表格线的位置，根据表格线的位置将待分割的栏目的图像提取出来。该方法具有实用性较强、对表格设计和印刷的要求较低的特点。

Abstract: A rapid layout analysis method of single-color table is introduced in this paper. The skew angle of table image is detected and adjusted by Radon transformation, then the positions of horizontal and vertical table-lines are found by projecting the table's image to the horizontal and vertical directions. The images of interested cells can be segmented by the table-lines surrounding them. This method has good practicability with low demanding on the designing and printing of tables.
