Procedimiento para estimar el color de materiales gonioaparentes

Abstract

Se divulga un procedimiento que estima el color de materiales gonioaparentes para cualquier dirección de luz incidente y observación a partir de un número pequeño de geometrías de medida. El procedimiento comprende: i) realizar medidas de la Función de Distribución Bidireccional de Reflectancia Espectral “BRDF” a geometrías preestablecidas; ii) aplicar un Análisis por Componentes Principales “PCA” a estas medidas; iii) expresar la BRDF como combinación lineal de autoespectros significativos; iv) comparar esta BRDF con un modelo físico dependiente de la función de distribución de los ángulos de orientación D ( Ɵ flake ) y d e las funciones aj (Ɵinc), que relacionan el color de los pigmentos con el ángulo de incidencia de la luz sobre los pigmentos; donde la comparación entre ambas expresiones permite determinar las funciones D(Ɵflake) y aj (Ɵinc) ya que la BRDF es igual en ambas expresiones y conocida; v) estimar el color del material gonioaparente.
