Modeling of axial underwater light filed of articial light source in clean water

The perception of the underwater light field of artificial light sources is important for aquatic 3-D reconstruction, hyperspectral imaging, etc. In this paper, a model of underwater light field is proposed, with the divergence properties and the attenuation by water taken into consideration. Experiments are conducted to verify the model. The result shows that the mean relative error of modeling is 1.15%.
