[Q] Hartley & Zisserman's book 3D reconstruction auto calibration equation solving
Are there any kind soul willing to give me any pointers to solve the Hartley & Zisserman's
3D reconstruction auto calibration equation for VARYING focal length; to solve focal lengths as well as plane at infinity parameters? I think I understand the equation, but I cannot solve the following set of nonlinear equations
Equation 19.3 or equation 19.4, varying focal length.. For fixed focal length, I found Pollefey's solution. But it seems his approach cannot solve this equation.
