We propose an advanced layering method of integrated dept-position map for real-world object. The depth map of far field object has not contain depth information and impossible to layering the far field objects. Therefore, the position map was rendered from generated high-quality 3D model used deep neural network, it is accurately layering for far field object. However, it has field loss of 3D model depending on the color density, when layering at near field. Therefore, by combining the depth map with the position map, the proposed integrated depth-position map was obtained for accurately layering in far and near field objects.
The improvement of fill factor of holographic micromirror array (HMA) with holographic waveguide-type for threedimensional (3D) augmented-reality (AR) display system. Our proposed 3D AR system was created and briefly explain it; there have two the HOE optical film at in-and out coupler of the waveguide. In-coupler HOE is our fabricated HMA, it has a same role with optical microlens-array. HMA is integrate the displaying elemental image set (EIS) from micro display which EIS was generated by the integral imaging technology. The micro display has a 6 mm by 8mm size, 48single elemental images and micro display was located g distance from holographic waveguide which waveguide thickness was 5mm. EIS was displayed by micro display to holographic waveguide. HMA was stick with holographic waveguide and located in opposite side of waveguide and micro display. Micro display was display forward to holographic waveguide and fabricated HMA, then displayed EIS is reflected and integrated at the in-coupler HMA and integrated 3D image was through the holographic waveguide by HMA recorded angle. 3D images of internal reflect in the holographic waveguide was 1 time. 3D image was also reflected at the out-coupler HOE which role was same as optical mirror and reflect to observer’s eye. At least observer as the reconstructed images and real object out and reflects by out-coupler HOE.
The waveguide-type full-color 3D-AR display system based on the integral imaging technique using the holographic mirror array is proposed. In the experiment, the AR feature has been successfully verified that the real-world scene and reconstructed virtual full-color 3D image were observed simultaneously.
