Abstract
PROCESSO DE MENSURAÇÃO DA REFLETÂNCIA E DISPOSITIVO. A presente invenção trata do campo da mensuração da cor, mais particularmente de um processo de espectrometria para medir a cor de um objeto que utiliza um dispositivo eletrônico, e do dispositivo associado. O processo de mensuração da refletância, difusa uniforme r (A) compreende as seguintes etapas colocação do referido objeto (30) em uma zona que se encontra em frente e sensivelmente perpendicular ao referido meio (11) e determinação pelo referido dispositivo (10) das duas funções desconhecidas contínuas ROBJ(lambda) e lext(lambda) resolvendo o sistema de equações integrando cada equação Ei na intersecção dos espectros fonte e sensor, designando por x, y e z as sensibilidades na base colorimétrica escolhida, e cada equação Ei gera então três equações Ei integrada, calculando o valor numérico que corresponde ao termo da esquerda das equações Ei integrada por meio dos parâmetros de saída do sensor numérico de imagem; e expressando as duas funções desconhecidas contínuas ROBJ(lambda) e lext(lambda) por meio de um número finito de pontos de interpolação ((lambda)j , yj) ligados por pelo menos uma função de interpolação s(lambda) para conservar o caráter contínuo das referidas funções desconhecidas contínuas ROBJ(lambda) e lext(lambda), sendo que (lambda)j são comprimentos de onda escolhidos na intersecção dos espectros fonte e sensor, sendo os parâmetros de entrada do processo escolhidos para minimizar o número de pontos de interpolação para uma determinada precisão; e buscando os parâmetros das funções ROBJ(lambda) e Iext(lambda) que minimizam o sistema dos mínimos quadrados ||A*X-B||2 que resulta das equações Ei integradas.
