Abstract

SISTEMA E MÉTODO PARA FORMAÇÃO DE IMAGEM DE OBJETOS REFLETORES. Um método e sistema para inspeção visual automatizada de um objeto incluem o uso de diferentes padrões de iluminação, cada padrão incluindo pulsos de frequência constante de iluminação. Os pulsos de cada padrão diferente de iluminação são temporariamente deslocados de modo a permitir a obtenção de imagens iluminadas por um ou outro padrão de iluminação. As imagens são combinadas usando diferentes partes das diferentes imagens nas quais a maioria dos detalhes do objeto está disponível, para produzir uma imagem completa do objeto que é essencialmente livre de brilho. O uso de pulsos de frequência constante permite obter imagens de iluminação de padrões diferentes, para permitir a criação de uma imagem livre de brilho de um objeto, enquanto provê um ambiente de inspeção livre de cintilação para trabalhadores humanos.
