基于Fast-NCC SFOC与小面元的全色—多光谱配准方法OA

Based on the unique imaging characteristics of domestic satellite panchromatic and multi-spectral image data and their significant spatio-temporal-spectral differences,we conducted an in-depth analysis of the causes of registration errors prior to image fusion and studied relevant registration methods.Addressing the issues of low efficiency in traditional manual registration and insufficient applicability of commercial software,we proposed a panchromatic and multi-spectral images registration method with high efficiency and high precision.By integrating Fast-NCC SFOC and tiny facet element differential correction technology,this method effectively corrects registration errors of domestic satellite panchromatic and multi-spectral images.This method was validated by Jilin-1 data from Anhui Province,China.The result demonstrates that the registration accuracy achieved by this method is better than one panchromatic pixel,providing important technical support for subsequent remote sensing applications of domestic satellites.
