当头部移动时，全息头戴式显示器需要生成新的运动视差全息图。此外，它是由许多运动视差图像组成的光场数据生成全息图所必需的。然而，重新绘制三维（3D）场景和重新计算全息图在计算上是复杂的。因此，我们提出了一种生成不同运动视差全息图的策略，无需重新绘制3D场景和重新计算全息图。该方法采用傅立叶带通滤波和简单的三角函数关系，使其能够跳过复杂的计算过程。
Generating new motion parallax holograms is required for holographic head-mounted displays when the head moves. Additionally, it is required for hologram generation from light field data that consist of a number of motion parallax images. However, re-rendering three-dimensional (3D) scenes and re-calculating holograms are computationally complex. Therefore, we propose a generation strategy of holograms with different motion parallax from an existing hologram without re-rendering 3D scenes and re-calculating holograms. The proposed method employs Fourier band-pass filtering and the simple relation of trigonometric functions, which makes it capable of skipping the computationally complex processes.
