相机拍摄的文档图像的透视校正 [英] perspective rectification of camera captured document image

问题描述

我正在做我的透视校正项目..
如果文档图像中存在感知力，某些机构可以帮助我在文档图像中找到消失点.我在想，如果知道消失点，我可以想出一种纠正图像中感知力的方法..任何人都可以..帮助我提供一些编码思想...

在某些文章中，我读到可以通过确定文档消失点中的局部偏斜来确定，但我不知道如何在图像中找到局部偏斜.是否可以在文档中找到局部偏斜..

i am doing my project on perspective rectification..
can some body help me to find vanishing point in the document image ,if it has perceptiveness present in it. i am thinking that if vanishing point is known, i can figure it out a way to rectify the perceptiveness in image.. any one plz plz.. help me with some coding ideas...

in some article i read that by finding the local skew in document vanishing point can be determined, but i don''t know how to find local skew in a image. Is it possible to find local skew in a document..

推荐答案

尝试边缘检测 [ ^ ]-看看是否能够找到大量指向相同点/区域的向量/线-您可能会发现多个消失"点.

最好的问候

Try edge detection[^] - and see if you''re able to find a number of vectors/lines pointing roughly to the same point/area - you''ll probably find more than one "vanishing" point.
