Problems solved by technology

[0010] There are two main problems in the above-mentioned three-dimensional display system: first, the cost is relatively high, because multiple projectors are required, regardless of whether front projection or rear projection is used, the price is relatively expensive; second, calibration is difficult, because such a display system It is difficult to require the image of each projector to be calibrated accurately

Embodiment 1

[0053] refer to Figure 4 , in Embodiment 1, Embodiment 1 of the true three-dimensional image display system of the present invention includes a surface light source 101 , an imaging device 102 , a digital light processing device 103 , a display screen 104 and a controller 105 .

[0054] Such as Figure 5 As shown, the surface light source 101 includes a plurality of unit light sources 101a arranged in a two-dimensional array for generating illumination beams, and the unit light sources 101a can be LEDs, lasers or xenon lamps.

[0055] The controller 105 controls the on-off of each unit light source. The position of each unit light source relative to the digital light processing device 103 is different, so the incident angles of the illumination beams generated by each unit light source incident on the digital light processing device 103 are different. In addition, since the multiple unit light sources 101a in the surface light source 101 are arranged in a two-dimensional arr...

Embodiment 2

[0068] refer to Figure 7 , in Embodiment 2, Embodiment 2 of the true three-dimensional image display system of the present invention includes a surface light source 201, an imaging device 202, a digital light processing device 203, a display screen 204, and a controller 205, and may also include a beam adjustment element 206 and The projection angle adjustment device 207, the components and their structural relationships in Embodiment 2 of the true three-dimensional image display system of the present invention are basically the same as the corresponding components and their structural relationships in Embodiment 1, the only difference is:

[0069] In Embodiment 2, the segmented projection lens array 208 between the display screen 204 and the imaging device 202 is used to project the image beam received by the corresponding imaging area of ​​the imaging device 202 onto the display screen for display, and the segmented projection The lens array 208 includes a plurality of proj...

Embodiment 3

[0073] refer to Figure 8 , in Embodiment 3, Embodiment 3 of the true three-dimensional image display system of the present invention includes a surface light source 301, an imaging device 302, a digital light processing device 303, a display screen 304, and a controller 305, and may also include a beam adjustment element 306 and The projection angle adjustment device 307, the components and their structural relationships in Embodiment 3 of the true three-dimensional image display system of the present invention are basically the same as the corresponding components and their structural relationships in Embodiments 1 and 2, the only difference is:

[0074] In Embodiment 3, the imaging device 302 is a segmented lens array, including a lens or a combination of lenses. The lens can be a single lens, and the combination of lenses can be a combination of multiple or multiple lenses. The lens or combination of lenses can be viewed from different angles. The received image beams are ...

Abstract

The present invention provides a true three-dimensional image display system and display method, wherein the system includes: a surface light source, a controller, a digital light processing device, an imaging device, and a display screen, and the controller controls the on-off of each unit light source so that the light emitted by the surface light source The illuminating light beam irradiates the digital light processing device at two different incident angles in two different directions; the digital light processing device receives the illuminating light beam irradiated at different incident angles in two different directions and modulates the illuminating beam to generate an image beam, and converts the image beam to Reflected to the imaging area of ​​the imaging device; multiple imaging areas of the imaging device image the received image beams from different angles to the display screen for display, which can generate a multi-field three-dimensional image display similar to that generated by multiple projector systems, and It has motion parallax in two different directions, only needs a single digital light processing device to realize three-dimensional display, and has convenient calibration, simple structure and low cost.

Description

technical field [0001] The invention relates to true three-dimensional display technology, in particular to a true three-dimensional image display system and display method. Background technique [0002] True 3D Volumetric Display Technique (True 3D Volumetric Display Technique) is a stereoscopic display technology. Each 3D pixel (voxel) of the displayed image has real surface characteristics and physical depth. Observing the displayed object presents a three-dimensional effect. [0003] The light field is a function that describes the luminous characteristics of an object in a certain area. Generally speaking, the light field function G(x, y, z, α, β, t), which is a six-dimensional function, where (x, y, z ) describes the three-dimensional position of the luminous point, (α, β) describes the luminous direction, and t is time. The light field function is even more complicated if various properties of light (such as polarity, phase, etc.) are taken into account. Starting f...
