[0002] In the field of underwater construction, underwater drilling operations are widely used in underwater concrete construction in multiple fields such as reservoir dams, ocean engineering, river bridge infrastructure, and seabed resource development. However, in the face of complex and variable underwater environments, especially in uneven terrain conditions, traditional drilling technology poses a serious challenge to the accuracy and efficiency of the operation. Existing underwater drilling solutions usually rely on divers to conduct underwater drilling and hole depth and hole spacing measurement operations based on personal experience. In shallow water environments, divers do not need decompression, and the underwater working time can be extended. The diver-by-diver measurement drilling scheme can also be implemented, but in deep water conditions, divers are not only affected by environmental factors such as deep water pressure and low visibility, but also have a significantly reduced working time. If divers work in deep water for a long time with high intensity, there is a high safety risk. In addition, the working time of divers is strictly limited in deep water conditions, which affects the continuity and efficiency of underwater operations.

[0003] During drilling, the positioning and stability of the drilling equipment are often disturbed by water flow, sediments, and surrounding uneven terrain. Without precise positioning and tracking technology, the accuracy of drilling will be greatly affected, which may result in deviation from the predetermined position, drilling depth error, or a series of problems such as sidewall collapse. These problems not only cause delays in the construction period, but also increase construction costs and affect the construction quality of subsequent processes.

[0004] In recent years, although some automated underwater drilling equipment has begun to be used gradually, most technologies have not effectively solved the problem of automatic positioning of drilling positions in uneven terrain and continuous operation.
