Abstract

MéTODO DE INSPEçãO E APARELHO PARA MARCAS IRREGULARES EM PNEU. A presente invenção refere-se a um método de inspeção de marcas irregulares em pneu capaz de julgar defeito da forma tridimensional da marca com uma confiabilidade maior sem depender da imagem de distribuição de brilho da irregularidade, e um aparelho de inspeção das marcas irregulares no pneu. O método de inspeção das marcas irregulares do pneu compreende uma etapa de medir as alturas da irregularidade inclusive das marcas a serem inspecionadas com relação a cada elemento de área em uma região de superfície de pneu predeterminada para adquirir dados de distribuição de irregularidade, uma etapa de especificar uma porção de superfície do pneu correspondendo a um modelo de marca na região de superfície do pneu a partir dos dados de forma tridimensional de um modelo de marca previamente preparado como um molde de cada marca e os dados de distribuição de irregularidade adquiridos acima, e uma etapa de determinar uma coincidência entre os dados de distribuição da irregularidade da porção de superfície do pneu especificados com relação a cada marca e os dados da forma tridimensional do modelo de marca para julgar uma aceitação da forma tridimensional da marca com base na coincidência.
