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.
