+### [`get3Dpoint.py`](https://github.com/bimalka98/Camera-Calibration-and-Backprojection/blob/M-CAIT-2013/get3Dpoint.py) script includes the implemetation of the mentioned paper to, backproject image coordinates back to the real world. When the equation of the plane where the real world objects lies, with respect to the real world coordinate system is known.
+
+> **Get equation of a plane is not a big deal when, a point lies on the plane and the normal vector to that plane are known.** 😉
