Research on Image Positioning of Underwater Operation System in Deep-Sea

In the deep-sea underwater environment, deep-sea underwater operations rely on image information to achieve accurate target positioning. In this paper, aiming at the refraction problem in the deep-sea underwater environment, based on the analysis of the underwater refraction model and binocular vision positioning principle, the refractive index is introduced to correct the refractive phenomenon; and aiming at the problem that the refractive index of seawater changes with water depth, temperature and salinity, the real-time calculation is carried out in the small operation environment relying on the auxiliary calibration method to achieve more accurate target positioning. The results of underwater experiments show that the above methods are effective and provide a reference for the accurate positioning of deep-sea underwater operations.
