Problems solved by technology

[0003] The traditional seabed terrain generation method only focuses on the processing of bathymetry data at unordered discrete points, does not consider the processing of continuous bathymetry data, and does not make good use of the association of continuous data to process seabed topographic data, especially when there is overlap in seabed measurement data. Inability to perform data fusion well, resulting in the generated seabed terrain not being able to truly reflect the topographical characteristics of the seabed

Embodiment Construction

[0057] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0058] The present invention is made up of AUV (Autonomous underwater vechle, unmanned unmanned submersible) and graphics workstation computer, wherein AUV needs to be equipped with a depth gauge and an altimeter sonar to measure the depth value of seawater, such as figure 1 shown.

[0059] The method of seabed terrain generation is as follows: figure 2 As shown, after the AUV obtains the data according to the survey line trajectory, it uploads the data to the computer of the graphics workstation, uses the seabed terrain data generation method for processing, and calls Vega after processing to model the seabed terrain and generate the seabed terrain, as shown in figure 2 shown.

[0060] According to the method of the present invention, the water depth data is processed on the graphics workstation computer, and finally the seabed topography...

Abstract

The invention discloses an automatic submarine topography generating method which can automatically generate submarine topography through water depth data obtained by an autonomous underwater vehicle (AUV). The method comprises two stages of the stage 1 of obtaining the water depth data through the AUV and the stage 2 of automatically generating the submarine topography according to the water depth data obtained by the AUV. The automatic submarine topography generating method is simple to operate and can effectively achieve the purpose of automatically generating submarine topography according to the water depth data obtained by the AUV. In addition, the generated submarine topography result can truly show the submarine topography characteristics.

Description

technical field [0001] The invention relates to the technical field of underwater robots, in particular to a method for automatically generating seabed topography by utilizing navigation data of an underwater robot. Background technique [0002] The navigation depth of underwater robots can reach thousands of meters, and the seabed terrain in the navigation area is complex. The existence of submarine reefs and submarine mountains poses a great threat to the navigation safety of underwater robots. However, the traditional electronic chart lacks topographic information on the seabed, so it is particularly important to automatically draw the seabed map in the robot's navigation area through data mining and fusion according to the navigation data of the underwater robot. When the underwater robot sails in the sea area for the first time, the navigation data is processed offline to automatically generate a seabed topographic map in the navigation area; when the underwater robot s...
