Real-Time Computer-Generated EIA for Light Field Display by Pre-Calculating and Pre-Storing the Invariable Voxel-Pixel Mapping

The elemental image array (EIA) for light field display, especially integral imaging light field display, was reliant on a virtual camera array, novel sampling algorithms, high-performance hardware or corresponding complex algorithms, which hinder its application. Without sacrificing accuracy and precision, we innovate a novel algorithm set to achieve video-level EIA generation. The invariable voxel to pixel relationship is pre-calculated and pre-stored as a lookup table or mapping. Benefiting from the very lookup table, the voxel array could be fast mapped to an EIA without contingent upon any high-end hardware.
