Opencv how to find the shift and rotation of an object in a frame?

Question

OpenCV

Good day!
There are two frames in which the desired object is present.
The first "template" frame, the second with camera rotation and shift.
Found an object in a template frame, selected it, made a "mask" (only this object is present, the rest is black).
I find the offset of the object using "phaseCorrelate", it turns out acceptable, but if there is also a rotation, then the offset (of course) is absolutely wrong.
How can you optimally find another turn?
PS I thought to translate both frames into polar coordinates and find the rotation using "phaseCorrelate", but the object is not in the center of the frame.
