Performance analysis of three-dimensional integral imaging systems based on human vision

In order to improve the assessment accuracy in three-dimensional integral imaging (3DII) in terms of avoiding misjudgments and facilitating choice-making, we propose a method to analyze performance of the 3DII systems based on human visual characters. The contrastive parameters are defined by calculating ratios of resolution and depth of the optical systems to those of the human vision respectively, which can present distinguishable visual difference between the 3DII systems with equivalent optical performance. Our analysis results indicate that the size of the lens array is closely related to the contrastive parameter of resolution. Furthermore, we also carry out experiments to verify consistency and reliability of the results for two different sets of 3DII systems as proposed in the study.
