Abstract:
In this paper we establish the relation between camera calibration and the generation of horizontal stereoscopic
images. After that, we introduce a new method that handles the problem of generating stereoscopic pairs
without using calibration patterns, instead we use the correspondence of homologous points. The method is
based on the optimization of a measure that we call Three-dimensional Interpretability Error, which has a
simple geometric interpretation. We also prove that this optimization problem has four global minima, one of
which corresponds to the desired solution. After that, we present techniques to initialize the problem avoiding
the convergence to a wrong global minimum. Finally, we present some experimental results.
