Do you have matlab code for this ? if yes let me know please .

the way :
The first thing to do is to solve the callibration matrix.
Once done, then you are able to project from 3D to 2D.
If you select points in 3D in which Z = 0, then your callibration matrix reduces to a 3x3 matrix, that could have an inverse, and then you can do measurements in 2D, and get the real values in 3D.
