摘　　要：研究Robert和Sobel等算子进行SST图像边缘检测,表明通用边缘检测算法无法在SST图像中提取温锋。提出一种基于网格运算的温锋提取算法,能较精确地在SST图像中提取温锋,并在Win环境下开发出实例并运行成功,证明该算法有效。Research Robert and Sobel arithmetic operators to detecting edge of SST image, results show that common edge detection can't fetch temperature front of SST image. An algorithm based on grid operation is brought out, which can fetch template front accurately. This algorithm has been developed in windows environment successfully, and experimental results demonstrate the effectiveness of the proposed algorithm.
