In recent years, underwater fine three-dimensional reconstruction technology has emerged as a focal point in research, exhibiting extensive potential applications, particularly in underwater archaeology and resource exploration. However, the application of existing technologies in underwater settings is confronted with certain limitations. Some sensors, such as cameras, possess the capability to capture color information, while others, like sonar and structured light, are adept at acquiring depth information. Nevertheless, the absence of a technique to effectively integrate these two sets of information hinders the achievement of highly faithful representations of underwater scenes. We aim to present targets as if they were revealed in front of observers after the removal of water, facilitating the precise capture of texture and color in underwater environment. Undoubtedly, the application of these technologies in underwater settings necessitates addressing challenges such as light attenuation, refraction, and color distortion.
