EFFICIENT NON-ANALOG MONTE CARLO SIMULATION OF UNDERWATER VISIBILITY AND IMAGING IN A COUPLED OCEAN-ATMOSPHERE SYSTEM
Accurate simulation of underwater vision and visibility under realistic environmental conditions remains computationally prohibitive, especially when the atmosphere, wind-agitated sea surface, and the water body are considered in a comprehensive radiative transfer model. Here, we present an efficient non-analog Monte Carlo framework for modeling solar radiative transfer within the coupled ocean-atmosphere system, applied to problems of underwater visibility and imaging. Our approach employs trajectory splitting to handle large optical depths, the conjugate trajectory method, and local estimators, and incorporates a stochastic facet model of the wind-agitated sea surface. Validation against numerical and in situ imaging experiments shows excellent agreement with established models, demonstrating the framework’s ability to predict underwater light fields, color transmission, and image degradation. The framework is able to substantially improve computational efficiency relative to analog Monte Carlo, by up to two orders of magnitude in optically thick cases, while maintaining controlled statistical error. The results show that non-analog Monte Carlo can serve as a practical and robust basis for modeling the coupled ocean-atmosphere system in problems of underwater vision.
