Abstract

Existen varios tipos de dispositivos plenópticos y conjuntos de cámaras disponibles en el mercado, y todos de estos dispositivos de adquisición de campo luminoso tienen su propio formato de archivo propietario. Sin embargo, no hay norma que soporte la adquisición y transmisión de información multi-dimensional. Es interesante obtener información relacionada con una correspondencia entre pixeles de un sensor de tal sistema de adquisición óptica y un espacio de objeto de tal sistema de adquisición óptica. De hecho, conociendo cual porción del espacio del objeto de un sistema de adquisición óptica de un pixel perteneciente al sensor de tal sistema de adquisición óptica se detecta permite la mejora de las operaciones de procesamiento de señal. La noción del haz de pixel, la cual representa un volumen ocupado por una serie de rayos de luz en un espacio de objeto de un sistema óptico de una cámara junto con un formato compacto para almacenar tal información por tanto se introduce.
