Abstract in Portuguese
Com o advento da Fotogrametria Digital nos últimos anos, a numerização de fotogramas através de scanners tornou-se uma etapa obrigatória nos processos fotogramétricos. Este trabalho tem como objetivo principal apresentar uma técnica de calibração de scanners, utilizando-se uma Transformação Afim de seis parâmetros com superabundância de observações. A metodologia proposta foi aplicada em três modelos de scanners diferentes e os resultados obtidos, nas condições experimentais, demonstraram uma boa adequação do modelo matemático proposto.

Abstract in English
With the approach of Digital Photogrammetry the last years, the digitizing of pictures through scanners has been an obligatory stage in photogrammetric procedures. The main purpose of this paper is to show a scanners calibration technique, by using an affine six-parameters transformation with redundancy. The proposed methodology was applied in three different models of scanners, and, in experimental states, the results gotten showed a good fit of the proposed mathematic model.
