Abstract: Due to the influence of complex underwater optical environment, the images obtained by underwater vehicles generally have degradation phenomena such as contrast attenuation, detail blur and color distortion caused by weak illumination, which seriously restricts the analysis of ocean environment. In order to deeply analyze the research progress of domestic and foreign scholars on underwater image processing under weak light conditions, the relevant literature in recent years is analyzed and summarized. Firstly, the causes of underwater weak light conditions are analyzed and the main problems to be solved are proposed. Then, the underwater image processing methods are classified according to the principles and characteristics of various algorithms. Secondly, starting from the main problems of underwater images under weak illumination conditions, the main characteristics and shortcomings of various algorithms are analyzed and summarized in detail. Then, the traditional algorithm and the underwater image processing method based on deep learning are compared and analyzed by designing experiments under low light conditions. Finally, some unsolved problems in the field of underwater image processing under weak illumination conditions are summarized, and the future research and development are prospected.
