说明：  影像匹配是指通过一定的匹配算法在两幅或多幅影像之间识别同名点的过程。它是图像融合、目标识别、目标变化检测、计算机视觉等问题中的一个重要前期步骤，在遥感、数字摄影测量、计算机视觉、地图学及军事应用等多个领域都有着广泛的应用。
(Image matching refers to the process of identifying the same point between two or more images by a certain matching algorithm. It is an important preliminary step in image fusion, target recognition, target change detection, computer vision and so on. It is widely used in remote sensing, digital photogrammetry, computer vision, cartography and military applications.)
