Abstract

In order to improve the capability of monitoring and predicting strong convective weather of Zhaoqing area, monitoring and early-warning system of strong convective weather is developed. Graphic and image technology is applied in the development of the system. The region growing method is used in image segmentation. The map of all towns of Zhaoqing area is drawn by coordinate transformation and graphics technologies. The processed radar image and the map of Zhaoqing area have been overlapped. By using improved arc-length method, the system can judge which areas are affected by strong convective echo.

图形图像技术在强对流天气监测预警系统中的应用

摘要

为了提高肇庆地区强对流天气的监测预报能力，开发了强对流天气监测预警系统。图形和图像技术被应用在系统的开发中。区域增长方法用于图像分割。通过坐标转换和图形技术绘制了肇庆地区所有城镇的地图。处理后的雷达图像和肇庆地区的地图已经重叠。通过使用改进的弧长方法，系统可以判断哪些区域受到强对流回波的影响。
