Abstract

La calibracion de un sistema de formacion de imagenes que tiene una camara (20) para capturar datos de color para un objeto meta (res 10) incluye una calibracion primaria con la que se obtiene una conversion primaria para los datos RGB que da lugar a una compensacion de las variaciones en la operacion o en las caracteristicas de la camara, y una calibracion secundaria con la que se obtiene una conversion secundaria que permite la compensacion de las condiciones de iluminacion locales durante la captura y el procesamiento de datos de color para el analisis de las imagenes captadas. La conversion primaria calculada relaciona los datos de color medidos reales con los datos de color estandar conocidos para los especimenes de color estandar particulares (31). Los especimenes de color estandar (31) se presentan en un cerramiento o cubierta (30) a la camara bajo iluminacion controlada e impidiendo que luz externa o extrana ilumine los especimenes. Una calibracion preliminar incluye calibrar los especimenes de color estandar de la calibracion primaria y la fuente de luz controlada asociada con respecto a los colores estandar de laboratorio centralizados.
