Researching on Underwater three-dimensional visual technology is one of the key technologies of deep-sea exploration and operating. This paper introduces the key technologies and development of underwater three-dimensional image survey technique, and proposes the high-speed access technologies for laser difference-frequency scanning three-dimensional image information, and man- machine interaction method of real-time display for depth information. The laser difference-frequency scanning three-dimensional visual technology can get the three-dimensional image information of the target in a high speed, and in the two-dimensional image, the depth information can be real-time displayed. So it is suitable for the underwater practical application.
