Abstract
Istotą wynalazku jest metoda wytwarzania fotoscenerii lotniczej symulującej porę nocną opierająca się na wykorzystaniu jednorodnego, 8 bitowego zobrazowania satelitarnego zapisanego w postaci RGB charakteryzująca się tym, że wykonuje się cyfrowe przetwarzanie zobrazowania RGB (obraz pierwotny Z(j,k)) równolegle w dwóch ścieżkach, gdzie ścieżka A polega na transformacji układu barw z RGB na IHS otrzymując obraz w kodowaniu IHS w postaci I1, H2 oraz S3, natomiast ścieżka B polega na tym, że obraz pierwotny Z(j,k) w postaci RGB poddawany jest najpierw operacji kontekstowej - splotu obrazu pierwotnego z maską Prewitt'a filtru gradientowego, a następnie poddawany jest filtracji morfologicznej poprzez operacje erozji otrzymując obraz ZPME, przy czym w kolejnym etapie obrazy otrzymane z obu filtracji w ramach ścieżki B zostają zsumowane w sposób: ZS = ZPME + ZP a wynikowy obraz ZS posiada składowe R', G' oraz B', po czym ostatnim krokiem jest selektywne połączenie wyników z obu ścieżek A i B polegające na wykonywaniu kompozycji obrazu poprzez kodowanie składowych poszczególnymi kanałami obrazów otrzymanych z obu ścieżek w taki sposób, że pierwszy i drugi kanał stanowi kanał Intensywności z obrazu IHS (ścieżka A), trzeci kanał kodowany jest kanałem czerwonym R' z obrazu ZS (ścieżka B).The essence of the invention is the method of producing aerial photoscenery simulating the night time based on the use of homogeneous, 8-bit satellite imaging saved in the form of RGB characterized by the digital processing of the RGB imaging (primary image Z (j, k)) in two paths simultaneously, where path A consists in the transformation of the color system from RGB to IHS, obtaining an image in IHS coding in the form of I1, H2 and S3, while path B consists in the fact that the original image Z (j, k) in the form of RGB is first subjected to a contextual operation - convolution of the primary image with the Prewitt mask of the gradient filter, and then is subjected to morphological filtration through erosion operations to obtain the ZPME image, while in the next stage the images obtained from both filtrations within path B are added together in the way: ZS = ZPME + ZP and the resulting ZS image has R ', G' and B 'components, then the last step is selective connection ie results from both paths A and B consisting in performing image composition by coding components with individual channels of images obtained from both paths in such a way that the first and second channels constitute the Intensity channel from the IHS image (path A), the third channel is coded by the red channel R 'from the ZS image (path B).
