This is a script for calculating the affine coefficients (taking acount of distortion inaccuracy).

Two cameras are capturing the images of night sky with stars.

Since the stars are far away (almost infinity, hehe), we may suppose that the scenes are the same, and the only difference is

in linear displacements, rotation (and distortion inaccuracy).

The user chooses the pairs of corresponding stars, get their coordinates (x1, y1) , (x2, y2). Several points are needed (at least 4), because we need to solve a system of linear equations

with the 7 unknown parameters = 6 (affine coefficients) + 1 (distortion correction coeff. of second[right] camera ).
