中文摘要：
由于不同静止气象卫星的观测时间、分辨率及红外通道的红外扫描辐射计的光谱响应函数和空间响应函数都不尽相同，因此，将两颗静止气象卫星的红外云图融合在一起而形成的多星拼图，就会在交界处呈现不连续性，图像上表现为一条明显的拼缝且拼缝的两边亮度不一致。本文利用“直方图匹配方法”对多星拼图进行处理，消除了亮度不均匀现象，提高了图像的整体视觉效果。
英文摘要：
Different stationary meteorological satellites have many different characteristics, such as time of observation, resolution, channel of infrared scanning radiometer, response function of spectrum and space. As a result of these differences,if we joint infrared cloud atlas of two different stationary meteorological satellites,it can be found that the junction of the two cloud atlas is discontinuous. In the mosaic picture,there is an obvious patchy gap,in the two sides of which the brightness is different. The mosaic picture is dealt with by histogram matching, and the asymmetry of the brightness is eliminated and the quality of the whole image is improved.
