Abstract

A new object tracking mask-based novel-look-up-table (OTM-NLUT) method is proposed and implemented on graphics-processing-units (GPUs) for real-time generation of holographic videos of three-dimensional (3-D) scenes. Since the proposed method is designed to be matched with software and memory structures of the GPU, the number of compute-unified-device-architecture (CUDA) kernel function calls and the computer-generated hologram (CGH) buffer size of the proposed method have been significantly reduced. It therefore results in a great increase of the computational speed of the proposed method and enables real-time generation of CGH patterns of 3-D scenes. Experimental results show that the proposed method can generate 31.1 frames of Fresnel CGH patterns with 1,920 × 1,080 pixels per second, on average, for three test 3-D video scenarios with 12,666 object points on three GPU boards of NVIDIA GTX TITAN, and confirm the feasibility of the proposed method in the practical application of electro-holographic 3-D displays.

摘要

提出了一种基于新的目标跟踪掩码的新型查找表（OTM-NLUT）方法，并在图形处理单元（GPU）上实现，用于实时生成三维（3-D）场景的全息视频。由于所提出的方法设计为与GPU的软件和内存结构相匹配，因此该方法的计算统一设备架构（CUDA）内核函数调用次数和计算机生成全息图（CGH）缓冲区大小已显著减少。因此，该方法的计算速度大幅提高，并能够实时生成3-D场景的CGH图案。实验结果表明，在所提出的方法中，在NVIDIA GTX TITAN的三块GPU板上，对于具有12666个目标点的三个测试3-D视频场景，平均每秒可以生成31.1帧1920×1080像素的菲涅耳CGH图案，并证实了该方法在电全息3-D显示实际应用中的可行性。
