Problems solved by technology

[0005] However, so far, there are still barriers to the commercial application of 3D visualization products
On the one hand, the 3D rendering algorithm involves a large number of parameters, which requires the support of a complete and friendly data call configuration scheme; on the other hand, the 3D rendering effect is different from the traditional 2D image perspective, and lacks a mature and systematic physical process graphic analysis template

Abstract

The invention discloses a three-dimensional visual typhoon analysis method. The method comprises the following steps: firstly, carrying out scalar rendering; carrying out vector rendering; and finally, carrying out spatial information fusion and carrying out playing according to a time sequence. Compared with a previous analysis method, the method has the following advantages that the method is simple, rich and visual, and in general, three-dimensional visualization is introduced into weather analysis work, so that service personnel can be helped to visually know the three-dimensional structure of a weather system, verify the accuracy of mode prediction, check the reliability of assimilation data, guide the construction and optimization of an observation station network and the like.

Description

technical field [0001] The invention relates to the field of meteorological analysis, in particular to a three-dimensional visualized typhoon analysis method. Background technique [0002] Accurately analyzing the three-dimensional structure of typhoons is of great significance for understanding the evolution process, intensity and range of typhoons and improving typhoon forecasts [1] . In many previous literatures, a wide variety of two-dimensional views have been designed for analyzing the three-dimensional structure of typhoons [2-4] , in order to restore the real three-dimensional typhoon structure as completely as possible with multi-view plane images. However, if the typhoon can be displayed stereoscopically in a three-dimensional image, many types of two-dimensional analysis image sequences can be visually represented in one image. [0003] In recent years, advances in sensing technology, data storage, computing power, and software structure have greatly enhanced t...
