opencv 3Dreconstruction期间的问题 [英] the problem during 3Dreconstruction with opencv

问题描述

我是一名研究生，使用opencv研究3D重建.假设我已经从左右摄像机获得了2D点，并且想计算3D点(XYZ).在书中，我知道使用cvperspectivetransform(或有人说cvreprojectimageto3D)，但我想知道世界坐标是怎么来的(似乎没有人建立它)?

I''m a postgraduate researching the 3D-reconstruction with opencv.Suppose I have get the 2D-points from left and right cameras and want to calculate the 3D-point(X Y Z).In the book I know using the cvperspectivetransform(or someone say cvreprojectimageto3D) ,but I want know how the world coordinate comes(It seems nobody built it)?

推荐答案

您的问题中有四个3D点. br/>
您在表示窗口坐标的平面上有两个相机点和2D点.在找到2D点的窗口平面上，应该有一种方法可以为您提供3D点.

这就是计算两条3D线所需的全部.

然后找到路口...

You have four 3D points in your problem.

You have the two camera points and the 2D points on the plane that represents the window coords. there should be a method that gives you the 3D point, on the window plane where the 2D point is found.

That is all you need to calculate two 3D lines.

Then find the intersection...
