Simulation of Upward Underwater Image Distortion Correction

Due to the effect of sea wave, the image captured by the camera underwater is not clear and the distortion. In order to pave the way for image correction and take corresponding measures to reconstruct the sea surface on the whole hemisphere image. This paper introduces the principle of Snell cone, analysis the principle of underwater imaging and proposes a method that along the Snell cone boundary element wave scattering calculation, obtain satisfies the linearized dynamic equations of wave height estimation, light path vector and fitting the whole image sequence, to estimate the wave ray tracing based on reverse. Furthermore, optical system model is built, and the light path through the air wave image generation is simulated by MATLAB. The simulation results show that, it can be used as a reference for the image distortion reduction of underwater imaging system.
