FPGA Architecture for Real-Time Ultra-High Definition Glasses-Free 3D System

This paper presents an FPGA architecture for real-time ultra-high definition (UHD) glasses-free 3D system by solving high bandwidth requirement and high complexity of the system problems. Video + Depth (V + D) video format and the depth-image-based rendering (DIBR) technique are supported by the system to reduce the requirement of bandwidth. In addition, an asymmetric shift-sensor camera setup is introduced to reduce the hardware cost as well as the complexity of the system. We also simplify the microlens array weight equations so as to reduce the complexity of subpixel rearrangement coefficients calculation for glasses-free 3D image creation. Experiments results show that the proposed architecture can support the resolution of 4K for real-time UHD glasses-free 3D display.
