【摘要】地震对于人类的生产生活有着巨大影响,如何准确地预测地震意义重大.利用FY-2D卫星云图序列图像研究了汶川地震前震区上空的地震云,在此基础上采用更高分辨率的MODIS数据进行地震云的检测研究,分别利用高斯马尔可夫场和高斯混合模型来实现云图的纹理分割和地震云异常检测.实验结果表明,此方法可有效检测出震区上空的地震云.%Earthquake has a huge impact on human life, how to accurately predict earthquakes is of great significance. The earthquake cloud over the area of Wenchuan is studed by FY-2D satellite cloud image sequences. On this basis, MODIS data with higher resolution is used for further verifying the earthquake cloud. Gaussian Markov Field (GMF) and Gaussian Mixture Model (GMM) are employed to achieve cloud texture segmentation and seismic anomaly detection respectively. Experimental results show that this method can effectively detect the earthquake cloud.
