仿射变换就是对应两个矩阵的坐标进行变换，得到112x112或112x96不同的size需要不同的变换矩阵，参见face_align_util.py

感谢回复，可能我之前的表述有误。
现在我有一套自己的关键点检测网络，不同于mtcnn采用的眼睛中心，这里我们采用了每只眼的两个眼角。
在计算变换矩阵时，由于关键点不同，就无法采用通用的五点坐标。在这种情形下，我希望针对我当前的关键点，重新统计一套标准脸的关键点坐标。
请问，这种情况下我该如何统计呢，或者说face_align_util.py中的arcface_src是如何统计的呢？

你可以按照平均正脸在112*112的坐标下找眼角的坐标，然后设置到转换矩阵中
