论文摘要
元素摄像机的设计需要两个不同的光学系统组合，即主镜头和一系列微镜。尽管常规摄像机的构造过程主要涉及将图像聚焦到单个平面上，但在元素摄像机的情况下，可能会有其他要求，例如预定义的野外深度或相邻微片图像中所需的差异范围。由于这种复杂性，手动创建多个元素相机设置通常是一项耗时的任务。在这项工作中，我们假设一个仿真框架以及给出的主要镜头数据，并提出了一种在不同约束集合集合下计算剩余的光圈，传感器和微卷阵列参数的方法。我们的基于射线追踪的方法显示出使模型优于其在图像质量方面使用常用的近似近似值产生的吊坠，同时仍达到所需的约束。实施和评估设置都可以公开使用，包括30个元素摄像头设计。
The design of a plenoptic camera requires the combination of two dissimilar optical systems, namely a main lens and an array of microlenses. And while the construction process of a conventional camera is mainly concerned with focusing the image onto a single plane, in the case of plenoptic cameras there can be additional requirements such as a predefined depth of field or a desired range of disparities in neighboring microlens images. Due to this complexity, the manual creation of multiple plenoptic camera setups is often a time-consuming task. In this work we assume a simulation framework as well as the main lens data given and present a method to calculate the remaining aperture, sensor and microlens array parameters under different sets of constraints. Our ray tracing-based approach is shown to result in models outperforming their pendants generated with the commonly used paraxial approximations in terms of image quality, while still meeting the desired constraints. Both the implementation and evaluation setup including 30 plenoptic camera designs are made publicly available.
