摘要: 在利用FY-2C气象卫星云图进行台风中心自动定位与跟踪的研究中,台风云系的分割是处理中关键的一步。结合台风主体云系具有灰度值较高、面积较大、活动范围有限和像素集中的特点,综合采用阈值法、数学形态学法和数理统计等方法,对FY-2C气象卫星云图中的红外一通道兰勃托原始投影云图中的台风分割进行了研究,取得了满意的效果。

Abstract: The segmentation of the typhoon galaxy is a crucial step in the processing of applying the FY-2C meteorological satellite cloud images for the study on automatic locating and tracking of the typhoon centre .In the article,in light of the main typhoon galaxy with the characters of higher grayscale value,bigger area,limited acting region and concentrated pixels,we comprehensively use threshold method,mathematical morphology techniques,mathematical statistics methods,etc,so as to research on typhoon segmentation of the original Lambert-projected cloud images from the first infrared channel of the FY-2C Meteorological Satellite.The results are satisfying.

Key words: satellite image, typhoon segmentation, central dense cloud region of typhoon
