Abstract

The invention relates to a true three-dimensional image display system and a true three-dimensional image display method. The true three-dimensional image display system comprises at least one image source, an optical compression device, an imaging screen, an optical device, and an optical scanning device. To be specific, the at least one image source is used for generating K view field image light beams. The optical compression device is used for compressing all view field image light beams to form H sets of compression image light beams; each set of compression image light beams includes K-column image light beams; and the K-column image light beams of each set of compression image light beams respectively are identical-column image light beams of the K view field image light beams. The imaging screen has H zones; each zone correspondingly receives one set of compression image light beams. The optical device has H imaging units; and each imaging unit emits the K-column image light beams of the compression image light beams projected to at all zones of the imaging screen to the K view fields respectively and correspondingly. And the optical scanning device is used for guiding the image light beams of the H sets of compression image light beams to the H zones of the imaging screen respectively. The K and the H are integers not less than 1. The provided system and the method have advantages of low cost, low calibration difficulty, and clear image.

Description

technical field [0001] The invention relates to image display technology, in particular to a true three-dimensional image display system and a true three-dimensional image display method. Background technique [0002] The so-called "true three-dimensional display" means that the relative positional relationship between the displayed three-dimensional objects is also truly reflected, forming a real three-dimensional space image, which has the surface characteristics of real physical depth and image quality, and the observer does not need any The auxiliary device can observe the displayed object arbitrarily from multiple directions, and perceive the most real and complete three-dimensional information. True 3D display technology fundamentally updates the concept of image display, makes the displayed image lifelike, provides complete psychological and physiological 3D perception information to the viewer, and provides a basis for understanding the spatial relationship between 3...
