Description

True three-dimensional image display systems and display packing
Technical field
The present invention relates to true dimension display technologies, relate in particular to a kind of true three-dimensional image display systems and display packing.
Background technology
Very three-dimensional (True 3D Volumetric Display Technique) is a kind of stereo display technique, the shown each three-dimensional picture point of image (voxel) has real character of surface and physical depth, observer is without any need for utility appliance, just can observe shown object from multiple directions, present stereoeffect.
Light field is to describe the function of object in a certain region characteristics of luminescence, in general, and light field function G (x, y, z, α, β, t), it is sextuple function, wherein (x, y, z) luminous point three-dimensional position is described, (α, β) describes light emission direction, and t is the time.If consider the various characteristics (such as polarity, phase place etc.) of light, light field function also can be more complicated.From light field theory, the target of real three-dimensional display system is exactly reconstruct as far as possible truly and reproduce the light field that real-world object generates, thereby observer is obtained and the three-dimensional perception of seeing that real-world object is similar.
With reference to figure 1, the light field function generating due to real-world object is the continuous function of space and angle, if simulated with multiple visual fields (multiview), needs the visual field of unlimited number, and Project Realization cannot be carried out in the visual field of unlimited.The principle of work of light field three-dimensional display system is to carry out with limited visual field (as visual field a-l) light field that approximate continuity distributes.Because human eye is limited to the resolution of space and angle, from the angle of perception and display effect, without the light field function of reconstruct continuous distribution.To the light field function of continuous distribution respectively along space, angle and time shaft carry out discrete sampling, carrys out simulated light field function with the visual field of limited number, is the starting point of light field dimension display technologies.
