Description
Technical Field
The invention relates to a three-dimensional meteorological radar data display method, and belongs to the field of computer data processing.
Background
The echo diagram of the meteorological radar is an important basis for a meteorologist to analyze meteorological data and make judgment and prediction. The traditional weather radar echo maps can be divided into two-dimensional display modes such as PPI (planar position indicator), CAPPI (contour position indicator), RHI (range height indicator) and the like. These patterns play a very important role in the atmospheric phenomenon analysis process. But atmospheric phenomena are actually a three-dimensional process of phenomena, and all two-dimensional display methods are display of a section of the phenomena. The two-dimensional display method cannot completely display the change of the whole meteorological process within the same time. With the development of computer technology, especially the development of three-dimensional display capability, three-dimensional weather display has become possible.
In practice, three-dimensional display methods are usually presented on the screen in a perspective mode. In the same direction, the data of different colors are mixed through Alpha to obtain a final color, and then the final color is displayed on a screen. This conventional fluoroscopy has two disadvantages: firstly, all the details are displayed, so that the video memory capacity of the computer is very tense; second, the final color values are affected by Alpha channel blending, so that the color of the inner layer will have some color deviation from the actual color values. In other words, the inner color value after Alpha blending has different visual perception, which affects the judgment of the meteorologist on the actual situation.
