Abstract

Método para calcular el "focal stack" asociado a un espacio objeto a partir de su función plenóptica, empleando una transformada de suma a lo largo de planos restringidos en hipercubos discretizados, lo que permite disminuir considerablemente el tiempo de cómputo. Se presenta además un método para aumentar la resolución del "focal stack" obtenido. Adicionalmente, la invención se refiere a dos métodos para recuperar en tiempo real las profundidades y los módulos y fases de la amplitud compleja del frente de onda, respectivamente, en cada posición de las superficies de una escena tridimensional, así como un sistema adaptado para realizar los métodos anteriores.
