Method for 3D light-field reconstruction based on a spatially free camera

Abstract

This study introduces an advanced algorithm for 3D light-field displays, utilizing disparity images from non-fixed cameras to achieve precise 3D reconstructions, moving beyond the complexities of traditional methods. Unlike standard approaches that depend on complex 3D reconstruction or specific camera arrangements, this algorithm uses pixel similarity across different viewpoints to determine depth accurately. It integrates camera parameters and light paths to restore light-field information meticulously, ensuring an optimal light distribution. By comparing with the projector image array (PIA) and display effects generated by traditional light-field encoding algorithms, we proved the effectiveness of our algorithm.
