中文摘要：

扭曲文本矫正过程中,文本行严重扭曲处恢复后,会出现单个文字仍然扭曲,且整行文字会在扭曲处发生文字拥挤现象,针对这一问题,提出一种基于三维数据的扭曲文档矫正技术。通过三维扫描仪采集文本三维数据,利用采集到的数据的自身特点,将三维数据的Z坐标高度差转化为文本行横向拉伸辗平距离,实现三维扭曲文本矫正。该方法能实现文本行的矫正,解决普通文本行矫正方法难以矫正的单个文字扭曲及文字拥挤问题。

英文摘要：

In the process of distorted text correction,after recovering the seriously distorted text line,single word distortion still exists and the whole text line is crowded in the seriously distorted area.To solve this problem,a distorted document correction technology based on 3Ddata was proposed.Text 3Ddata were collected using 3Dscanner,the characteristics of the collected data were utilized,and the 3Ddata of height of Z coordinate structure were transformed into the text line transverse stretching distance,so as to realize the three dimensional distorted text correction.This method can not only achieve text line correction,but also solve the single word distortion and crowding that cannot be solved using ordinary text-line distortion correction method.
