A fast-direct pixel mapping algorithm for displaying orthoscopic 3D images with full control of display parameters

We propose a fast-direct pixel mapping method for the solution of the pseudoscopic problem in integral imaging (II) three-dimensional display. After processing the conventional captured elemental image array (EIA) to crop the “effective area”, direct pixel mapping can be applied to synthesize orthoscopic EIA within a short time. The display parameters such as pitch, focal length, gap and elemental lens number of the micro-lens array and 3D image depth can be set arbitrarily, so the proposed method can make an II film suitable for different II monitors. No reference plane is set in the method, so there is no depth error. The simulation and optical experiments reconstruct the 3D images with correct depth, which verifies the proposed method.
