本文提出了一种使用纯相位相关（POC）的图形处理单元（GPU）实现立体对应匹配的方法。使用基于POC的高精度立体对应匹配使得利用立体视觉测量物体的精确3D形状成为可能，而基于POC的方法的缺点是计算成本较高。为了解决这个问题，我们提出了一种基于 POC 的对应匹配的 GPU 实现。通过使用各种 GPU 的一组实验，我们证明了与 CPU 实现相比，所提出的实现展示了基于 POC 的立体对应匹配的高速和高效计算。我们还将所提出的实现应用于两种类型的 3D 测量应用并证明其有效性。
This paper proposes a Graphics Processing Unit (GPU) implementation of the stereo correspondence matching using Phase-Only Correlation (POC). The use of high-accuracy stereo correspondence matching based on POC makes it possible to measure accurate 3D shape of an object using stereo vision, while the drawback of POCbased approach is its high computational cost. Addressing this problem, we propose a GPU implementation of POC-based correspondence matching. Through a set of experiments using a variety of GPUs, we demonstrate that the proposed implementation exhibits high-speed and high-efficiency computation of POC-based stereo correspondence matching compared with the CPU implementation. We also apply the proposed implementation to two types of 3D measurement application and demonstrate their effectiveness.
