Abstract

The invention provides a long-distance naked-eye stereoscopic display method and a system thereof. Scene segmentation of original three-dimensional image data and rendering of oversampling processing are matched with fusion processing in a display process, high-dimensional space information of the original three-dimensional image data is segmented and rendered to a plurality of to-be-modulated two-dimensional image data, and a display fusion algorithm in time and a ray modulation method are utilized to fuse the two-dimensional image data of a to-be-displayed three-dimensional image into a high-dimensional light field in order to carry out three-dimensional display. According to the method and the system, the hardware requirements of long-distance naked-eye stereoscopic display for the system can be effectively reduced, and the to-be-displayed long-distance three-dimensional image data is segmented into multiple parts of space information; the fusion is carried out in the display process through time-sharing refresh in order to increase the display density of the space light field, and the stereoscopic display effect of the surface can be effectively improved in order to increase the depth of three-dimensional display, so that the purposes of large depth range, vivid stereoscopic impression, high pixel resolution and fast display speed of the displayed three-dimensional image are realized.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional display, and more specifically, to a long-distance naked-eye stereoscopic display method and system thereof. Background technique [0002] At present, naked-eye three-dimensional display methods include three-dimensional display methods such as holographic display technology, volumetric display technology, cylindrical lens and grating binocular parallax display technology, and three-dimensional holography. Naked-eye three-dimensional display methods represented by holographic and volumetric display technologies have problems such as large volume and large amount of data in the process of stereoscopic display with a long display depth, which is not conducive to real-time interaction and other operations. Naked-eye 3D display methods such as cylindrical lens, grating, and stereoscopic hologram technology have obvious advantages in display speed and data processing capacity, but are...
