  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.
