Abstract
Patente de Invenção: <B>"PROCESSO DE INSPEçãO DE SUPERFìCIE DE UMA TIRA EM DESLOCAMENTO POR CLASSIFICAçãO PRéVIA DE IRREGULARIDADE DE SUPERFìCIE DETECTADA"<D>. Nesse processo de inspeção de superfície de uma tira em deslocamento, formar-se com o auxílio de meios de captação de imagens, pelo menos uma imagem digital de pelo menos uma das faces da tira (10), filtra-se a dita pelo menos uma imagem digital para a detecção de irregularidades de superfície e trata-se pelo menos uma imagem digital filtrada para a identificação do tipo de defeito de superfície que corresponde a cada irregularidade detectada. Previamente à etapa de tratamento das imagens digitais, caracteriza-se as irregularidades determinando-se para cada uma delas o valor de parâmetros, predeterminados característicos de defeitos de superfície e efetua-se uma classificação prévia das ditas irregularidades, a partir dos valores determinados dos ditos parâmetros, de acordo com um conjunto de classes predefinidas, a dita etapa de tratamento sendo efetuada em cada classe.
