Description
Technical field
The utility model relates to true dimension display technologies, relates in particular to a kind of true three-dimensional image display systems.
Background technology
Very three-dimensional (True3D Volumetric Display Technique) is a kind of stereo display technique, shown each three-dimensional picture point (voxel) of image has real character of surface and physical depth, the observer is without any need for utility appliance, just can observe shown object from a plurality of directions, present stereoeffect.
Light field is to describe object at a function of a certain regional characteristics of luminescence, in general, the light field function G (x, y, z, α, β, t), it is sextuple function, wherein (x, y z) describe the luminous point three-dimensional position, and (α β) describes light emission direction, and t is the time.If consider the various characteristics (such as polarity, phase place etc.) of light, the light field function also can be more complicated.From the 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 the observer is obtained and the three-dimensional perception of seeing that real-world object is similar.
