Simulation of underwater objects imaging through rough sea surface based airborne laser range-gated system

摘要

A model is currently being developed for simulating images of underwater objects as seen by airborne laser range-gated (LRG) system. The simulation model is based on physically accurate models of wind generated waves on the sea surface, and the optical properties of ocean water. It can take as input any digital image and simulate its degradation due to scattering in water and through the wavy sea surface. This paper describes the model implementation for LRG system and presents the results of simulations. Simulation results presented here allow the visual evaluation of image quality for different depth and optical properties of the sea water. These simulations will also allow us to develop optimal strategies for image processing algorithm of Lidar data.
