摘要:

根据中尺度对流系统(MCS)的识别判定标准,基于数字图像处理和模糊模式识别等技术,研究对MCS云团的自动识别与追踪。利用SUSAN边缘检测算子提取边界轮廓,并以亮温直方图结合云团的多个特征量构建追踪模板,实现云团追踪。通过对2014年5月10日12~17时的追踪实验发现,该方法可快速实现MCS云团的自动识别,并能实现对多时次MCS云团的连续有效追踪。

关键词: MCS, 图像处理, 亮温直方图, 贴近度

Abstract:

According to the criteria of the identification of mesoscale convective system (MCS),this paper researches on identifying and tracking MCS automatically by means of image processing and fuzzy pattern recognition technology.The SUSAN edge detector is used to extract the boundary contour,thus realizing cloud tracking via building tracking templates with brightness temperature histograms and multiple cloud cluster characteristics.The experiments on tracking MCS during the time 12 to 17 hour of May 10,2014 show that the method has the ability of identifying MCS automatically and quickly and tracking MCS of multitime effectively.

Key words: MCS;image processing;brightness temperature histogram;close degree
