Marine environment information three-dimensional visualization method

Abstract

The invention discloses a marine environment information three-dimensional visualization method, belonging to the field of a three-dimensional visualization technology. The method comprises the following steps: step 1, establishment of a three-dimensional earth model; step 2, three-dimensional visualization realization of marine environment information data, wherein the step 1 comprises three steps of data preprocessing, data hierarchy partitioning and three-dimensional earth model generation; and the step 2 comprises three steps of marine environment information data preprocessing, drawing of three-dimensional images and displaying of the three-dimensional images. By utilizing the visualization technology, the three-dimensional visualization of the marine environment information is realized, the three-dimensional earth model is constructed, and a micro background field is provided for the vivid and visual expression of the marine environment information; and by combining the characteristics of the marine environment information and aiming at marine environment factors of different types, different three-dimensional visualization methods are designed, thus the marine environment information is expressed more vividly and realistically, working personnel can analyze more visually, and the marine environment information can be utilized better.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional visualization, and in particular relates to a method for realizing three-dimensional visualization of marine environment information with a three-dimensional earth model as a background field. Background technique [0002] In recent years, with the emphasis on marine development, various new technologies and means have been used for marine observation and data acquisition, thus accumulating a large amount of marine environmental information data. How to effectively use marine environmental information has become an important research topic, and how to intuitively and visually express marine environmental information and its changing trends has become the focus of research. [0003] Along with people's increasingly diverse and massive information needs in the process of ocean development, the original two-dimensional ocean environment information has been increasingly unable to meet the n...

Problems solved by technology

At present, although 3D visualization technology has some applications in marine environmental information, it is still at the primary level, and there is no patent for research on 3D visualization of marine environmental information. Dong Wen et al. In "Technical Research", only the 3D visualization of marine scalar field elements on the sphere was studied, but the 3D visualization of vector field elements was not considered
