Abstract

Niniejsze zgłoszenie przedstawione na rysunku zapewnia sposób i urządzenie do korygowania zeskanowanego obrazu oraz układ do skanowania obrazu i dotyczy dziedziny skanowania obrazu. Sposób obejmuje: uzyskanie zeskanowanego obrazu skanowanego obiektu; wykrycie jednego albo większej liczby obiektów odniesienia z zeskanowanego obrazu; określenie parametru zniekształcenia każdego obiektu odniesienia jednego albo większej liczby obiektów odniesienia na podstawie ustawionego wcześniej standardowego parametru każdego obiektu odniesienia; oraz skorygowanie zeskanowanego obrazu w oparciu o parametry zniekształcenia jednego albo większej liczby obiektów odniesienia. Dzięki wykryciu na zeskanowanym obrazie obiektu odniesienia, zeskanowany obraz jest skorygowany w oparciu o parametr zniekształcenia obiektu odniesienia, tak aby rozwiązać problem zniekształcenia zeskanowanego obrazu i poprawić efekt wykrywania.
