回答1：

设置参数的时候不能只设置一幅图的下面那一幅图也要设置并选Adjust
具体：对边缘羽化后的图像进行影像镶嵌，具体操作步骤如下：在ENVI 主菜单Basic Tools 菜单中选择Mosaicking→Georeferenced，打开Map Based Mosaic 窗口，开始进行基于地理坐标的镶嵌操作。Import→ ImportFiles，加载需要进行镶嵌的影像数据；加载完图像后，选中一幅图像，点击右键，选择Edit Entry，打开Entry 窗口，将Data Value to Ignore 改为0，羽化距离设置为10，将参考图像选为Fixed，其它图像全为Adjust；完成编辑后，选择File→ Apply，打开Mosaic Parameters 窗口，将重采样改为三次卷积内插法（Cubic Convolution），像元大小设置为30 米，输出影像mosaic.img。

因为你黑边可能不是0,所以你忽略设置为0也不行，你先检查一下，黑边的值，然后忽略这个值就行了
