标题：TRANSFORMAÇÃO AFIM NO PLANO E AFIM PARALELA PARA A CORREÇÃO GEOMÉTRICA DE IMAGENS IKONOS NO PROCESSO DE MONORRESTITUIÇÃO DIGITAL PARA A ATUALIZAÇÃO CARTOGRÁFICA DE MAPAS MUNICIPAIS NA ESCALA DE 1:25.000
摘要：This paper shows the results of mathematics models, affine and parallel affine (APM), that was employed to geometric correction of IKONOS image for it updates municipal maps, on scale 1:25.000 in the mono-plottering process. The affine is the mathematic model usually employed for differents softwares of Computer Aidded Designed (CAD), Desktops and Geographical Informations System (GIS) for processing digital images. This model is employed to modeler the deformations of rotations, translations and scale that occur in the IKONOS images, without consider the inflence of the relievo. The parallel model is a degeneracy of 3D affine transformation, whose projection center is moved to the infinite. This 3D model permits the ortho-rectification of images features that they have unkowning parameters. This paper analyses the residuals behaviours of control points and check points, presented for the geometric correction of IKONOS images, in the digital mono-plottering process with the mathematics models of parallel affine and affine in 2D, with 9 control points and elevations data are derived from maps with 10m of equidistants, The qualifies parameters was employed for these are Class A defined for Edicted 89817 of 1984. The final answer demonstrated that the affine model wasn’t unpropitious for scale 1:25.000, and the parallel affine. Then the parallel affine model was aproved for the update cartographic methodology in the mono-plottering in the digital process.
