Detecting plane Angle from object Orientation

I need to determine the plane angle with reference to coin orientation in image, any advices and help is welcome

first, find an ellipse that fits the outline of the coin.

please elaborate, thank you

you should google for docs and tutorials before asking.

see if you can get that applied to your picture.

next you’ll need to understand how circles appear as ellipses when projected. hint: the centers do not coincide. knowing the two axes (and diameters) of the ellipse should be good enough for what you need.

yes, working on it, thanks for your input, it really helped me alot,
