Voltage-sharing field identification method and device, storage medium and terminal

Abstract

The invention discloses a voltage-sharing field identification method and device, a storage medium and a terminal. The method comprises the following steps: acquiring meteorological prediction data of a to-be-identified region on longitude and latitude coordinate points in a future preset time period; performing data expansion according to the meteorological prediction data on the longitude and latitude coordinate points to generate high-resolution matrix data; constructing an isobaric matrix image, and fusing the isobaric matrix image with the high-resolution matrix data to generate three-dimensional matrix data; and inputting the three-dimensional matrix data into a pre-trained voltage-sharing field identification model, and outputting a voltage-sharing field identification result corresponding to the to-be-identified region. According to the method, the high-resolution matrix data and the isobaric matrix image are fused into the three-dimensional matrix data in another form, so that a channel of non-image data and image data is opened, the trained model is combined with the three-dimensional matrix data to perform automatic analysis of the voltage-sharing field, automatic identification of the voltage-sharing field in meteorological services can be realized, and the accuracy of the analysis of the voltage-sharing field in the meteorological services is improved. Therefore, the identification efficiency of the voltage-sharing field is improved.

Description

technical field [0001] The invention relates to the technical field of automatic identification of weather systems, in particular to a method, device, storage medium and terminal for identifying a pressure equalization field. Background technique [0002] The pressure equalization field is a kind of surface weather in which the pressure change is so small within a range that the wind formed by the pressure gradient force cannot be formed, and its vicinity is often accompanied by important weather systems and weather phenomena, such as the occurrence of The wind was weak, resulting in a hazy weather. With the frequent occurrence of disaster events caused by pressure-equalization fields, pressure-equalization field activities have received extensive attention. Therefore, pressure-equalization field analysis has become an important task in weather forecasting. [0003] In the existing pressure-equalization field analysis scheme, the pressure-equalization field analysis is stil...

Because manual analysis takes the forecaster's valuable business time and is subjective, the accuracy of the analysis results is reduced

[0004] patent application CN112131958A provides a method for automatically identifying the southwest vortex, by automatically identifying the southwest vortex in the high-altitude isobaric surface, and using digital image methods to identify the southwest vortex The analysis of the key features of the low vortex can complete the automatic identification of the southwest low vortex. Due to the large and wide range of the high-altitude isobaric surface, there are omissions in the key features extracted by the digital image method, so that the extracted features cannot fully represent the weather characteristics. As a result, the accuracy of recognition is low and the recognition efficiency is reduced.
