I have a image on which there is object (square). I need to create matrix5x5 of this object, but it can be rectangle. I need to do it fast and without OpenCV or OpenGl, only using standarts libs of python I can detect coordinates of corners

  • I'm a bit surprised you want a 5×5 matrix, as I'd expect 3×3 for a planar setup or 4×4 for three-space. See also [Finding the Transform matrix from 4 projected points (with Javascript)](https://math.stackexchange.com/q/296794/35416) or [Redraw image from 3d perspective to 2d](https://stackoverflow.com/q/14244032/1468366) or [How to match 3D perspective of real photo and object in CSS3 3D transforms](https://stackoverflow.com/q/36050537/1468366) for questions on how to find a certain projective transformation. Is this what you want? – MvG Dec 04 '17 at 20:56
