Abstract
The invention discloses transverse wide-visual field tridimensional display method and system based on a spliced light field. The method comprises the steps of: obtaining image sources necessary for aligned observation of different view points in the transverse direction of a tridimensional scene; utilizing a plurality of projection display units to project a planar directional diffuser screen in an alignment manner; and enabling an observer to move along the transverse direction to view different transverse parts of the tridimensional scene spliced by vertical images formed by the aligned projection of different projection display units so as to realize transverse wide-visual field tridimensional display. The system comprises a projection tridimensional display unit, a planar directional diffuser screen and a control computer. The projection unit is structured by pixel region division of a two-dimensional display unit and a corresponding lens and aperture array right ahead, and the planar directional diffuser screen is projected in an alignment manner.

Description
Technical field
The present invention relates to 3 D displaying method, relate in particular to a kind of horizontal wide view-field three-D display packing and system based on the splicing light field.
Background technology
Display technique just develops towards the direction that high-resolution, three-dimensional panorama show.3-D display is different from the conventional two-dimensional demonstration and brings visual depth perception through the whole bag of tricks to the beholder exactly, makes its nature and the third dimension degree information that obtains artificially in the picture.The lot of domestic and foreign dimension display technologies can be divided into generally that hologram three-dimensional shows and two kinds of non-holographic 3-D display.Hologram three-dimensional shows that because of it be the information record of very three-dimensional and the 3-D display mode that demonstration is described as future ideality; But needing high-resolution spatial light modulator and superfast data handling system aspect the dynamic demonstration; These two factors have greatly limited this development of technology makes it can not get into practical application well, is only applicable to the picked-up and the demonstration of still image at present.Therefore the non-holographic 3-D display is present main flow display technique, and realizes that the non-holographic dimension display technologies generally can be divided into body 3-D display, integration imaging 3-D display, stereoscopic 3-D display etc.Body 3-D display and stereoscopic 3-D display all have display device appearance preferably at present, yet mostly rely on rotating screen to satisfy the demand that full visual angle is watched based on the display device of body 3-D display, so display device structure relative complex cost is also higher; Though bore hole has considerable commercial promise from stereoscopic 3-D display, only be provided at mostly and realize the high-resolution 3-D display in the limited view-angle coverage.Then there is the problem that much needs solution in aspects such as number, picture crosstalk, the viewing area degree of depth and size to traditional integration imaging dimension display technologies at the visual angle.
The projection bore hole three-dimensional display apparatus of present invested in plantization is complex structure mostly, needs a large amount of projector and control circuit, and big often cost and labyrinth bring laterally limited observation visual field, therefore lacks concrete practical application.And problems such as single naked-eye stereoscopic display images displayed resolution is low, the visual angle is few and discontinuous, depth feelings is not enough more make it use in the virtual reality field and lack innovation.Fundamental purpose of the present invention is to make up one, and expansion is strong, cost is controlled, and has the space three-dimensional display device of very big field range, and satisfies the demand that many people watch from various visual angles.Its advantage is watched the 3-D view suspension effect that possesses fine and smooth transverse parallaxes before being to be created in plane directional scattering screen.Fine and smooth visual angle can be brought the three-dimensional perception of continuous no saltus step to the observer at interval, reduces the discontinuous sense tired out that brings in visual angle in the conventional 3-D display.The structure of planar lightfield splicing projection display unit and plane directional scattering screen has enlarged transverse field on the basis of having simplified system architecture greatly.Utilize the mode of modularization multi-screen splicing to realize the expansion of transverse projection visual field simultaneously, can increase the horizontal space yardstick of 3-D view greatly.
