Problems solved by technology

[0003] Because the existing EPISM method uses the observation point O instead of the holographic unit to obtain the effective viewing angle image slice, there will be stitching errors in the reconstructed image, which will affect the accuracy of the holographic volume view.

Abstract

The invention discloses a method and a system for acquiring a holographic stereogram. The method comprises the steps of: acquiring all holographic units of a dry plate; dividing an LED panel into a plurality of sub-blocks according to the size of the holographic units of the dry plate, wherein the size of the sub-blocks is the same as the size of the holographic units; determining a number and positions of effective viewing angle image slices of the virtual dry plate according to the holographic units and the sub blocks; embedding all the effective viewing angle image slices to obtain an embedded image; and recording the embedded image onto the dry plate to obtain the holographic stereogram. The method and the system can eliminate splicing errors and obtain the holographic stereogram withhigh quality.

Description

technical field [0001] The present invention relates to the field of holographic volumetric views, in particular to a method and system for acquiring holographic volumetric views. Background technique [0002] Holographic stereoscopic printing technology is a holographic technology that has been widely used in medical, exhibition, military, art and many other fields. Since Dennis Gabor invented holographic technology in 1948, holographic printing technology has experienced transmission holographic printing, reflective holographic printing, etc. Holographic printing, holographic volume printing, computational holographic printing, wavefront holographic printing and a series of developments, among which the most widely used is the holographic volume printing technology. [0003] In the existing EPISM method, because the observation point O is used instead of the holographic unit to obtain the effective viewing angle image slice, there will be splicing errors in the reconstruct...
