Simulation framework for evaluating lightweight spectral cameras in drone-based aquatic sensing applications.

Optical remote sensing of aquatic environments using aerial drones is becoming more feasible as lightweight, low-power, spectral cameras increase in availability. Use of these cameras in such applications involves complex trade-offs in optical design and in deployment strategies, and simulations provide a means to examine this multidimensional design space to identify specific limitations on performance for a given measurement scenario. In this paper, such a simulation framework is developed, and its use in two realistic aquatic remote sensing scenarios is explored. Such a framework can provide insight into not only uses of existing camera systems, but also aspects of optical design or hardware that would lead to improved accuracy when using such cameras aerially over natural water bodies.
