Abstract

The invention discloses an alignment method for an underwater vehicle, and the method comprises the following steps: obtaining a target image of a target region, the target region comprising a light-emitting laser light source; extracting a region of interest corresponding to the laser light source in the target image; performing shape recognition on the region of interest to obtain a shape recognition result of the region of interest; and controlling the underwater vehicle to be aligned with the laser light source based on the shape recognition result and the region of interest. The invention further discloses an alignment device, the underwater vehicle and a computer readable storage medium. By means of the alignment method, the motion range of the underwater vehicle is large.

Description

technical field [0001] The invention relates to the field of underwater positioning, in particular to an alignment method, device, underwater vehicle and computer-readable storage medium. Background technique [0002] Underwater laser communication has the characteristics of long distance, high precision and good real-time performance, and the dynamic and precise alignment and precise tracking of laser beams are the basic guarantees for stable underwater communication. [0003] At present, in order to achieve accurate underwater alignment, in the existing alignment methods, a fixed reference object is usually arranged underwater, and the positional relationship between the mobile node (such as an underwater vehicle) and the fixed reference object is used to control the mobile node. , to achieve the alignment of mobile nodes. [0004] However, with existing alignment methods, the range of motion utilizing mobile nodes is small. Contents of the invention [0005] The main ...
