Laser guiding device for underwater docking

Abstract

The invention discloses a laser guiding device for underwater docking. The device comprises a can-be-modulated laser module, a parallel collimation module, a high speed two-dimensional scanning galvanometer, a central processing module and a laser reception module, wherein the high speed two-dimensional scanning vibrating mirror is controlled by the central processing module for making the can-be-modulated laser module emit laser to form a spatial conic scanning laser beam, an angle code of the spatial conic scanning laser beam is acquired through a photoelectric detector, the angle code acquired by the photoelectric detector is read and analyzed by an underwater navigation device end, and then the angle information relative to a docking platform can be acquired through querying the pre-set information, self attitude is continuously adjusted according to the angle information, the underwater navigation device end moves to the docking platform to accomplish docking, and the underwater searching success rate is improved.

Description

technical field [0001] The invention relates to a laser guiding device, in particular to a laser guiding device for underwater docking. Background technique [0002] With the development of science and technology, more and more attention is paid to the development of the ocean. Due to the limitation of human physiological conditions, most of the work of underwater development needs to be completed with the help of underwater equipment. As an indispensable Tools, more and more valued, have broad application prospects and important scientific research value. However, limited by the size and mass, the energy carried by the underwater vehicle is very limited, and it must establish a connection with the docking platform to replenish energy and exchange information during long-term operations. At present, there are two commonly used underwater docking guidance methods. One is the sonar-based navigation-guidance-docking integration method, which directly uses the navigation equipm...

Problems solved by technology

Although this method has a long range, the accuracy of sonar guidance is low, and a complex mechanical structure is required to ensure the reliability of docking in the short-distance docking type

The other is the guided docking method based on visual servoing. This method requires high-quality imaging of landmarks and high-precision data measurement algorithms as technical support, so the implementation cost is high and the solution is more complicated.
