Three-dimensional reconstruction method based on meteorological radar base data

Abstract

The invention relates to the meteorological field. In order to improve the intuitiveness of meteorological data, the inside structure of a monomer is reproduced by aid of two-dimensional image information through certain three-dimensional visualization algorithm and enabled to be three-dimensional, and potential information of meteorological radar base data is excavated to the maximum so as to provide an initiative data display mode and relevant meteorological features for meteorological research activities. According to the technical scheme of a three-dimensional reconstruction method based on the meteorological radar base data, the method includes the following steps: (1) extraction and sampling of fault contour lines, which include binaryzation processing on images, performance on boundary smooth denoising through opening operation, small area removal through zone marking, and boundary tracking for boundary extraction and chord sampling for boundary sampling; (2) three-dimensional modeling of the monomer, which includes contour correspondence between faults, contour splice between the faults, interpolation and furcation processing between the faults; and (3) three-dimensional rendering and display based on an open graphics library (GL). The method is mainly applied to the meteorological field.

Description

technical field [0001] The invention relates to the field of meteorology, and performs three-dimensional reconstruction based on basic data obtained by weather radar, and specifically relates to a three-dimensional reconstruction method based on weather radar basic data. Background technique [0002] Weather forecasting has always been an important task related to people's livelihood and livelihood. Over the years, many relevant scientific and technical personnel have devoted themselves to research in the field of meteorology, hoping to help forecasters make accurate and timely forecasts of weather, especially severe convective weather, and reduce losses caused by natural disasters. At present, most of the research work in all meteorological fields is carried out in two-dimensional space, which lacks intuition and low degree of visualization. For this reason, the present invention is devoted to the modeling research of three-dimensional space. [0003] For computer visuali...

Problems solved by technology

Visualization technology has been widely used in many fields. However, most of the visualization system software developed at home and abroad are based on two-dimensional image display. With the development of science and technology, these can no longer meet the needs of people's scientific research and work.
