Abstract

processo e dispositivo de análise de qualidade de uma vidraça e processo de fabricação de uma vidraça. o processo de análise da qualidade de uma vidraça, notadamente vidraças automotivas, de acordo com a invenção, compreende: uma etapa de geração de uma imagem numérica de um alvo (4) produzida em reflexão pela superfície externa da vidraça (2) do lado externo da vidraça (2), o alvo (4) apresentando um motivo composto de uma pluralidade de elementos contrastados definindo entre si linhas de interface; uma etapa de cálculo de grandezas representativas da vidraça (2) a partir da imagem gerada, p cálculo sendo efetuado por uma unidade de tratamento (8); e uma etapa de comparação dos valores calculados para as grandezas representativas em relação aos valores de referência. as grandezas representativas são representativas de uma deformação da imagem do alvo produzido em reflexão pela superfície externa da vidraça (2).
