Intermediate Unknowns
2. The vector of unknowns is m = (m1, m2, m3, m4, m5):
m1=r11/ty     m2=r12/ty      m3=r21/ty      m4=r22/ty      m5=tx/ty
where the r’s and t’s are unknown rotation and translation parameters.
3.  Let vector b = (u1,u2,…,un) contain the u image coordinates.
4.  Solve the system of linear equations
                            A m = b
for unknown parameter vector m.
