Abstract

"MéTODO DE AJUSTE DA RESPOSTA DE ESCALA DE CINZA DE UM SCANNER E PROCESSO DE FABRICAçãO EM QUE UM PRODUTO FABRICADO é ESCANEADO POR UMA PLURALIDADE DE SCANNERS DE ESCALA DE CINZA". A presente invenção provê um método de ajuste da resposta de escala de cinza de um primeiro scanner e de um segundo scanner, de modo que as duas respostas de escala de cinza mais proximamente combinem uma com a outra. O método inclui a etapa de provisão de um primeiro scanner que tem uma resposta de escala de cinza quando do escaneamento de um alvo. Também, um segundo scanner é provido, que tem uma resposta de escala de cinza quando do scanner do alvo que é ajustável. A resposta de escala de cinza do primeiro scanner é medida quando do escaneamento do alvo. Também, a resposta de escala de cinza do segundo scanner é medida quando do escaneamento do alvo. Adicionalmente, a transportador de cinta do segundo scanner é ajustada de modo a combinar mais proximamente com a resposta de escala de cinza do primeiro scanner.
