Abstract

Implementation for signal processing in a three-dimensional (3D) image system with multi vision capturing and holographic reconstruction is reported. In the implementation, we utilize a graphic processing unit (GPU) in stead of a central processing unit (CPU). This is because a GPU is specialized for image processing and it can execute parallel processing. In this research, the processing to generate hologram patterns from a set of 3D data obtained by analysis of multi vision is implemented on a GPU. We compare processing times of GPU implementation and CPU one. As a result, it is shown that the former implementation can complete the process faster than the latter. In the best case, the processing time with the GPU is 600 times as short as that with the CPU.
