内置功能可在OpenCV中组合仿射变换吗? [英] Built in function to combine affine transforms in OpenCV?

问题描述

Opencv中是否有结合仿射变换的内置函数?
我也可以自己编写，但是在可能的情况下我会坚持使用库函数.

Is there any built-in function in Opencv which combines affine transforms?
I can write it by myself too, but I'd stick to using library functions when possible.

干杯.

推荐答案

现在我这样做:

• 我分配了a1，a2，r个矩阵，所有3x3眼，
我用转换矩阵a1aff，a2aff替换了前两个的顶部.
• r = a2 * a1
• 返回r的前两行.

• I allocate a1, a2, r matrices, all 3x3 eyes,
• I replace the top part of the first two with the transformation matrices a1aff, a2aff.
• r = a2*a1
• return the first two rows of r.

此解决方案将立即执行.

This solution will do for now.
