Embodiment 1
[0028] Such as figure 1 As shown, a tilting multi-view floating panoramic space three-dimensional display device based on a combined screen includes: a transmission combined deflection type scattering screen 1, a high-speed projector 2, an image control module 3, a rotation detection module 4, a motor 5 and Transmission mechanism 6.
[0029] The transmissive deflecting diffuser screen 1 is composed of a plurality of transmissive deflective diffuser screens 11 with different main deflection angles. Each transmissive deflector diffuser screen 11 corresponds to a pitch viewing angle. The structure of each transmission deflection type scattering sub-screen 11 is as follows figure 2 As shown, it consists of a transmissive sawtooth grating 111 and a first cylindrical grating 112, the transmissive sawtooth grating 111 is located below the first cylindrical grating 112, and the transmissive sawtooth grating 111 and the first cylindrical grating 112 The grating directions are parall...
Embodiment 2
[0041] Such as Figure 4 As shown, another tilting multi-view floating panoramic space three-dimensional display device based on a combined screen includes: a high-speed projector 2, an image control module 3, a rotation detection module 4, a motor 5, a transmission mechanism 6 and a reflection combined deflection Type diffuser screen7.
[0042] The reflective deflection type scattering screen 7 is assembled and spliced by multiple reflective deflection type scattering sub-screens 71 with different main deflection angles, and each reflective deflection type scattering sub-screen 71 corresponds to a pitch viewing angle. The structure of each reflective deflection type scattering sub-screen 71 is as follows Figure 5 As shown, it is composed of a reflective sawtooth grating 711 and a second cylindrical grating 712, the reflective sawtooth grating 711 is located below the second cylindrical grating 712, and the reflective sawtooth grating 711 and the second cylindrical grating...
