How to find the distortion of a quadrangular figure (perspective, tilt angle) in relation to the rectangle?

Question

Algorithms

Good evening.
There is a contour with 4 points. It is always a rectangle, but it can be distorted in the picture (shown from different angles). There are essentially two types of distortion: tilt and perspective. We need an algorithm to find how much the rectangle is distorted. This is necessary in order to impose another rectangle with text on this contour, which, accordingly, will need to be distorted in the same way.

Example

Any suggestion?
Thanks in advance.

Answer 1

You need to look towards perspective image distortion .
