# UIPerspective，透视变换

(下面是数学公式，如果数学公式渲染不出来的话换个浏览器吧)

$$\begin{pmatrix}
u'&v'&w'
\end{pmatrix}=\begin{pmatrix}
u&v&w
\end{pmatrix}\begin{bmatrix}
a_{11}&a_{12}&a_{13} \\
a_{21}&a_{22}&a_{23} \\
a_{31}&a_{32}&a_{33}
\end{bmatrix}=\begin{pmatrix}
u&v&w
\end{pmatrix}\begin{bmatrix}
T_1&T_2 \\
T_3&a_{33}
\end{bmatrix}$$
$$uv为原图，x'y'为变换后的结果$$
$$T_1=\begin{bmatrix}
a_{11} a_{12} \\
a_{21} a_{22}
\end{bmatrix}表示图像线性变换$$
$$T_2=\begin{bmatrix}
a_{13} a_{23}
\end{bmatrix}^T表示图像透视变换$$
$$T_3=\begin{bmatrix}
a_{31} a_{32}
\end{bmatrix}表示图像平移变换$$
