问题描述

给定的点的三维(X =(X1,X2,X3),Y =(Y1,Y2,Y3)),我怎么能适应转变,从X到Y?

Given set of points in 3D ( X = (x1, x2, x3), Y = (y1, y2, y3) ), how can I fit transformation from X to Y?

据我所知,这就是所谓的投影变换。
下面是例如,X和Y的。

As far as I know this is called projective transformation.
Here is example of X and Y.

蓝放在X红色线是平行的,但它们不是Y中平行。

Blue and red lines in X are parallel, but they are not parallel in Y.

推荐答案

在3D投影变换有一个相关的4x4矩阵(模常数乘法)。你可以找到矩阵最小二乘法拟合。

Projective transformations in 3d have an associated 4x4 matrix (modulo a constant multiplication). You can find the matrix with least square fitting.
