摘要

This study presents a three-dimensional (3-D) integral imaging system to improve concurrently the viewing angle, Depth-Of-Focus (DOF) and resolution of the reconstructed object images by using multi-directional projections and non-uniform lenslets array with Intermediate-View Reconstruction Method (IVRM). In this method, each elemental lens array collects multi-directional illuminations of multiple Elemental Image (EI) sets and generates multiple Point Light Sources (PLSs) at the different positions in the two focal planes. The viewing zone and depth-of-focus is larger than the conventional method because of multi-directional projections of multiple EI sets and non-uniform lenslets; whereas a conventional method produces a viewing zone using only a single set of EI projection and uniform lenslets. For the non-uniform lenslets, DOF-improved integral images of 3-D objects can be picked-up and then by applying the IVRM to these picked-up integral images. Hence, the viewing angle, DOF as well as resolution enhanced object images can be reconstructed. To find out the possibility of the proposed system, experimental results are discussed with mathematical expressions.
