单应性用于什么？ [英] What homography used for ?

问题描述

您好。我有一个问题..

我使用的是冲浪法，它正在绘制单应性，我不知道单应性用于什么..

所以我想知道使用什么单应性为？非常感谢你



我尝试了什么：



我有尝试搜索谷歌回答我的问题，但我仍然不知道什么单应性用于

Hi. I have a question..
I used surf method and it is drawing homography, and i dont know what homography used for..
So i want to know what homography used for ? Thank you so much

What I have tried:

I have tried Searching google to answer my question, but i still dont know what homography used for

推荐答案

单应性 - Google搜索 [ ^ ]

一个非常简单的谷歌（我试过什么是单应性用于？）会立即给你答案 - 这是我搜索的顶部链接：

A very simple Google (I tried "What is homography used for?") would have given you the answer pretty much immediately - this was the top link from my search:

引用：

在计算机视觉领域，空间中同一平面的任何两个图像都是由单应性（假设针孔相机模型）。这具有许多实际应用，例如图像校正，图像配准或相机运动旋转的计算以及两个图像之间的平移。一旦从估计的单应矩阵中提取了相机旋转和平移，该信息可以用于导航，或者将3D对象的模型插入到图像或视频中，以便以正确的视角渲染它们并且看起来已经是原始场景（见增强现实）。

In the field of computer vision, any two images of the same planar surface in space are related by a homography (assuming a pinhole camera model). This has many practical applications, such as image rectification, image registration, or computation of camera motion—rotation and translation—between two images. Once camera rotation and translation have been extracted from an estimated homography matrix, this information may be used for navigation, or to insert models of 3D objects into an image or video, so that they are rendered with the correct perspective and appear to have been part of the original scene (see Augmented reality).

将来，请尝试自己做至少基础研究，不要浪费你的时间或我们的时间。

In future, please try to do at least basic research yourself, and not waste your time or ours.
