Abstract :
In this paper, a 2D-to-3D video conversion system capable of realtime conversion of 1920×1080p 2D video to 3D video is presented. System fuses global and local depth generation modules to generate depth image, and use depth image based rendering(DIBR) algorithm to render 3D video. The system is implemented both on software and hardware. Software is based on multi-core system with CUDA platform. To optimize performance, several techniques are proposed, including unified streaming dataflow, multi-thread schedule synchronization, and CUDA acceleration. Real-time 1920×1080p 2D-to-3D video conversion system running at 30fps is achieved.
