This paper introduces the image fusion approach of multi|resolution analysis|based intensity modulation (MRAIM) to produce the high|resolution multi|spectral images from high|resolution panchromatic image and low|resolution multi|spectral images for navigation information infrastructure. The mathematical model of image fusion is derived according to the principle of remote sensing image formation. It shows that the pixel values of a high|resolution multi|spectral images are determined by the pixel values of the approximation of a high|resolution panchromatic image at the resolution level of low|resolution multi|spectral images, and in the pixel valae computation the M|band wavelet theory and the à trous algorithm are then used. In order to evaluate the MRAIM approach, an experiment has been carried out on the basis of the IKONOS 1 m panchromatic image and 4 m multi|spectral images. The result demonstrates that MRAIM image fusion approach gives promising fusion results and it can be used to produce the high|resolution remote sensing images required for navigation information infrastructures.
