英文摘要： For the characteristics of large amount of data in high-definition real-time computer-generated holographic three-dimensional display, this project analyzes the relationship between the human visual system resolution and hologram information. Based on the simplification of three-dimensional objects and hologram compression, data compression coding methods of the high-definition real-time three-dimensional objects are studied. The design of low complexity, highly efficient parallel data compression algorithms is applied to the computer-generated holographic three-dimensional display system, to achieve a monochrome computer-generated holographic three-dimensional display with an object space of 1280×0×0 and a refresh rate of 25 frames per second. The amount of data of the computer-generated holographic three-dimensional display can be effectively reduced by implementation of this project, and the generation speed of CGH can be improved. So that high-definition real-time computer-generated holographic three-dimensional display becomes possible, and the technology of computer-generated holographic three-dimensional display is practical, to meet the national demands for key technologies and application systems of large-scale real three-dimensional display.
