Remote sensing image fusion is a technology of combining multi-source remote sensing image data through image processing technology. Its purpose is to combine the multi-band information of a single sensor or the information provided by different types of sensors to produce more accurate, complete and reliable estimation and judgment than that of a single information source. Its advantages are improving the spatial resolution and definition of images, improving the accuracy of plane mapping and classification, enhancing the ability of interpretation and dynamic monitoring, and effectively improving the utilization of remote sensing image data.
