Description
Technical field
The present invention relates to dimension display technologies field, more particularly to a kind of filled based on the body Three-dimensional Display for circumferentially shielding scanning
Put and method.
Background technology
Since in recent years, the new display skill of future generation that dimension display technologies and equipment are greatly developed as each developed country
Art, is increasingly becoming the frontier science and technology field of hot topic.Compared with two dimension display, 3 D stereo is shown with more depth perception, stereovision
And the sense of reality, observer is produced psychological cognition by visually-perceptible, obtain more abundant information.Three-dimensional stereo display technique
In machine vision, virtual display and augmented reality, 3D TVs, 3D films, 3D game, or even military, medical imaging, educate and navigate
The fields such as empty space flight, have broad application prospects.
If display inherently solid, so that the three-dimensional body presented has physical depth.So in display
When do not need any auxiliary equipment（Such as glasses, the helmet etc.）Come help people observe 3-D view, such people just can as
Equally direct 360 ° of full views are to the stereo-picture of " true " in actual life, and this technology is referred to as true 3-D technology.
Existing true three-dimension display technlolgies include hologram three-dimensional Display Technique, integration imaging dimension display technologies, light field Three-dimensional Display skill
Art and body dimension display technologies etc..Hologram three-dimensional display is recorded using the method for interference record diffraction reconstruction and is reconstructed mesh
Mark whole wavefront informations such as intensity, phase and wavelength of light.Integration imaging Three-dimensional Display passes through liquid crystal panel and cylinder light
Grid (or cylindrical lens array) combination realizes that light of the guiding comprising specifying information enters certain observation area, produces and each viewpoint
Corresponding image, realizes Three-dimensional Display.Light field Three-dimensional Display by shadow casting technique and directional screen control light information and
Exit direction, realizes the reconstruction of optical wave field of target object, and compared to holography display, the light field three-dimensional dependent on PC Rendering is aobvious
High-resolution dynamic and the three-dimensional scenic with complex texture can be realized by showing.
Body Three-dimensional Display（Volumetric 3D display）It is that one kind can really have width, height at one
With the technology that image information reproduction is carried out in the true three-dimension space of depth, also referred to as space loaded and displayed（Space filling
display）.Body Three-dimensional Display includes dynamic scanning type and static state is illuminated.It can be divided into again from screen illumination mode actively luminous
With passive illumination mode, active illumination mode includes LED array rotation sweep or translation scan, multilayer liquid crystal overlapped way,
Based on upper conversion body fluorescent material illumination mode etc.；Passive illumination mode include laser scanning or project at a high speed plane screen or
The mode of person's spiral screen reconstructs the luminous voxel of full angle, and the three-dimensional body of reconstruct is transparent.
In scan-type body Three-dimensional Display, whether screen is actively luminous or passive luminous, is required to quickly translation screen
Curtain or Rotation screen, and the display content of the conversion two dimension screen of high speed, to realize voxel（voxel）Display.Utilize translation screen
Swept-volume show it is one of implementation method.Its principle is as shown in Figure 1.
As shown in Fig. 2 during dynamic translation swept-volume is shown, the stereo-picture to be shown is projected with the mode of two dimension slicing
Onto the screen of a translational motion, the speed that the screen can not be discovered with observer is in motion, due to the persistence of vision of human eye,
So as to form three-dimensional body in human eye.Therefore the very three-dimensional aobvious of image can be realized using the three-dimensional display system of this technology
Show.It is screen translational motion structure imaging space to translate swept-volume Display Technique, be exactly a flat screen along it is vertical it
The axle of plane moves reciprocatingly structure imaging space, and the amplitude of motion determines the depth of field of imaging space.
Relative to rotary screen, this translation, which moves back and forth scanning, can ensure that the voxel size of Three-dimensional Display is uniform,
There is no central shaft and dead band, and image is directly projected, and is not likely to produce error, be can be very good to improve picture quality, is reduced system
Complexity.
It is reciprocal to need but the problem that screen moves back and forth scanning is that the motion process of screen is not uniform motion
Ceaselessly acceleration and deceleration process, voxel renewal frequency when voxel renewal frequency will match uniform motion during acceleration and deceleration is to ensure three-dimensional
Display is undistorted.Therefore the projection frequency of high speed projection arrangement also will be by accurate calculating, to match the reciprocating motion rail of screen
Mark, adds system complexity.Or only projected as shown above at the uniform velocity area, so waste substantial amounts of three-dimensional aobvious
Show the depth of field, make voxel points reduction.
