In the article we present various theoretical and experimental approaches to the problem of stereo matching and disparity estimation. We propose to calculate stereo disparity in the moments space, but we also present numerical and correlation based methods. In order to calculate disparity vector we decided to use discrete orthogonal moments of Chebyshev, Legendre and Zernike. In our research of stereo disparity estimation all of these moments were tested and compared. Experimental results confirm effectiveness of the presented methods of determining stereo disparity and stereo matching for machine vision applications.

W artykule przedstawiono teoretyczne i eksperymentalne podejścia do problemu pasowania i oceny niezgodności stereoskopowej. Zaproponowano realizacje obliczeń niezgodności stereoskopowej w przestrzeni momentów otrogonalnych, jak również przedstawiono podstawy do obliczeń numerycznych i metod opartych na korelacji. W celu obliczania wektora niezgodności zdecydowano się na użycie dyskretnych momentów ortogonalnych Chebysheva, Legendre'a i Zernike'a. W procesie badawczym oceny niezgodności stereoskopowej wszystkie proponowane momenty były testowane i porównywane. Wyniki badań potwierdzają skuteczność prezentowanych metod określania niezgodności i pasowania stereoskopowego dla zastosowań widzenia maszynowego.
