This paper introduces an improved image registration method for infrared and visible remote sensing image based on NSCT and SIFT algorithm. As the infrared and visible spectral characteristics of remote sensing images are inconsistent, the gray difference between these two images are quite distinct, so there are less matching points by using SIFT algorithm directly. The method of NSCT can decompose...
Double-sided rotating scan mirror is adopted by infrared camera of HJ-1B satellite as its imaging mode. With the support of knowledge for infrared camera, satellite ephemeris file and attitude file, a rigorous sensor model for infrared camera of HJ-1B is constructed. Meanwhile, in consideration of the positioning error caused by inaccuracy of ephemeris and attitude, an error reduction model used to...
