Abstract

método de controle do aspecto da superfície de um pneumático. a presente invenção se refere a um método de detecção de uma anomalia na superfície de um pneumático compreendendo as etapas seguintes ao longo das quais: a - realiza-se a imagem de uma anomalia dada presente na superfície de pelo menos um pneumático, b- com o uso de uma coleção de filtros, constrói-se, em um espaço de filtros, uma imagem multivariada da superfície mencionada, na qual cada pixel é representado sob a forma de um vetor pixel, as componentes de cada vetor pixel possuindo um valor correspondente ao valor deste pixel na imagem transformada com o uso de cada um dos filtros da coleção, c- com o uso de uma função linear, transforma-se essa imagem multivariada do espaço de filtros em um espaço espectral de dimensão da cujas variáveis são os filtros ou combinações de filtros da coleção mencionada, para formar uma imagem espectral, d - constrói-se um classificador determinando-se, para esta anomalia, as zonas representativas do espaço espectral da anomalia mencionada transformada no espaço espectral mencionado.
