Abstract
A method for performing a convergence calculation using a projective transformation between images captured by two cameras to observe a flat part of an object in the images, wherein a computational load is reduced while securing a convergence property of the convergence calculation. Initial values (n(), d()) are set to values satisfying a limiting condition that should be satisfied by the initial values (n(), d()), where the limiting condition is that a plane πa(i) defined by the initial values (n(), d()) of given types of parameters (n(i), d(i)) of a projective transformation matrix in the convergence calculation is inclined with respect to an actual plane including the flat part of the object to be observed.
