表格图像转换成Word表格的研究

Research on Converting Table Image into Word Form

随着计算机技术的不断发展,电子表格在信息存储领域扮演着日益重要的角色。把纸质表格扫描成图像后利用图像处理技术把图像中的表格提取出来,实现纸质表格到可编辑Word表格的转换。首先,将纸质表格进行扫描并保存为图片,然后运用BRISK方法对表格图像进行特征点检测;接着进行透视变换,实现表格图像的倾斜校正,之后对表格图像进行预处理,然后按照形态学处理的方法分离表格图像内的横线和竖线,并对横线和竖线图像进行修复和细化,利用角点检测提取表格横线和竖线的端点坐标;最后,按照表格图像中横线和竖线的端点坐标在Word中绘制表格。通过图像处理技术实现纸质表格到电子表格的转换。

With the continuous development of computer technology,spreadsheets are playing an increasingly important role in the field of information storage.By scanning paper table into an image and then extracting the table from the image by image processing technology,the conversion from paper table to editable Word table is realized.First,scanning the paper form and saving it as image.Second,the BRISK method is used to detect the feature points of the table image,and then the perspective transformation of the table image is carried out to realize the tilt correction of the table image.Third,preprocessing the form image,then separating the horizontal and vertical lines in the table image with the morphological processing method,repairing and refining the horizontal and vertical line images afterward,and extracting the endpoint coordinates of the horizontal lines and vertical lines with corner detection.Fourth,drawing the table in Word according to the endpoint coordinates of the horizontal and vertical lines in the table image.Thus the conversion from paper forms to spreadsheets with image processing technology is achieved.
