Abstract

MÉTODO DE AVALIAÇÃO DAS SUPERFÍCIES DE UM PNEUMÁTICO Processo de avaliação das superfícies de um pneumático moldadas com elementos rígidos, no qual se constitui uma coleção de N imagens de uma zona dada do pneumático a partir das imagens provenientes de um ou vários pneumáticos, cada uma das imagens da coleção sendo constituída pelos valores de grandezas físicas medidas por um sensor sensível à reflexão da luz em cada um dos pontos de coordenadas i, j da referida superfície, e depois faz-se corresponder por superposição as imagens da referida coleção, e compara-se a imagem da zona de um pneumático da referida coleção a avaliar com uma imagem de referência caracterizado pelo fato de que se calcula o valor das grandezas físicas da imagem de referência a partir do valor de cada uma destas grandezas físicas medida sobre as N imagens da referida coleção.
