Embodiment Construction
[0056] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0057] The visualization method of the marine environment provided by the present invention, such as figure 1 As shown, in view of the shortcomings of the existing multi-dimensional visualization methods of the marine environment, the parallel coordinate method in visualization mining is introduced into the multi-dimensional data expression of the marine environment, and a multi-dimensional data visualization method of the marine environment based on 3D scenes and parallel coordinates is developed. The key algorithm for consistent rendering and interactive data extraction integrated into 3D scenes and parallel coordinates; through the combination of multi-dimensional visual expression methods in 3D scenes and parallel coordinates, the comprehensive expression of multi-dimensional marine environment data that is consistent in time a...

Abstract
The invention discloses an ocean environment visualization method. Based on the combination of the ocean environment three-dimensional scene and a parallel coordinate method, the method comprises the concrete steps of modeling the three-dimensional scene and the parallel coordinates of ocean environment; secondly establishing a multi-dimensional element integrated rendering and interactive extraction algorithm based on the three-dimensional scene and the parallel coordinates of the ocean environment; thirdly expressing the multi-dimensional ocean environment data linked features and cluster features. The method can be used for knowledge discovery of ocean phenomena such as storm tides, red tides, ENSO circulation and the like, and provides a new idea for understanding, rebuilding and discovering ocean phenomena.
Description
technical field [0001] The invention relates to a visualization method of multidimensional data, in particular to a visualization method of multidimensional data about marine environment. Background technique [0002] The ocean is a typical multi-dimensional dynamic environment, including time dimension, space dimension, and marine environmental element dimension. The marine environment element dimension includes: sea and air elements, specifically such as clouds, rain, fog, air pressure, temperature, etc.; sea surface elements, specifically such as wind, waves, currents, tides, storm surges, etc.; marine water body elements, specifically such as Temperature, salinity, density, internal wave, circulation, climatic layer, etc.; and seabed elements, such as geology, landform, magnetic field and other environmental elements. [0003] Disasters such as storm surges, red tides, and sea ice on the mesotemporal and spatial scales, oceanic and atmospheric carbon dioxide fluxes on t...
