Abstract

Abstract

Since the observation ability of underwater imaging systems is limited in the environment of low illumination and turbid water, the experimental scheme of the pool was designed from the perspective of an auxiliary illumination source. The influence of spectral characteristics of illumination source on scattering characteristics of water medium under different turbidity conditions was analyzed. The analysis of measured data shows that the scattering coefficients of water bodies are different under the auxiliary illumination sources with different colors. The scattering coefficient of blue light is larger in water with low concentration, and the imaging with blue light is not ideal. The scattering coefficient of red light is larger than that of blue light with increasing concentration. The research results not only help to optimize the parameters of illumination sources in underwater imaging systems but also provide strong technical and theoretical support for applying de-scattering methods and obtaining high-quality underwater observation videos.
