Abstract

The invention discloses a satellite-borne multi-spectral remote sensing image fusion method based on super-resolution enhancement. The method comprises: acquiring RGB multi-spectral images and carrying out re-sampling processing; acquiring multi-frame full-color images and performing super-resolution reconstruction to obtain a high-resolution full-color image; carrying image registration on each image among the resampled multi-spectral images and the high-resolution full-color image to obtain registered multi-spectral images; and carrying out feature conversion on the registered multi-spectralimages to obtain fused multi-spectral images. According to the method disclosed by the invention, the spatial geometric resolution of multi-spectral images can be improved and the optical system design difficulty can be reduced only by using the multi-spectral images and full-color image having the same spatial resolutions; and the micro-nano satellite multi-spectral remote sensing data have thegreat application value.

Description

Technical field [0001] The invention relates to the technical field of remote sensing data processing, in particular to a spaceborne multispectral remote sensing image fusion method based on super-resolution enhancement. Background technique [0002] Image fusion refers to the integration of multi-band information from a single sensor or multi-source heterogeneous data information provided by different sensors to make up for the shortcomings of a single data source and eliminate possible redundancy and contradictions between multi-sensor information to form A clear, complete and accurate information description of the target. An efficient image fusion method can comprehensively process multi-source data information as needed, thereby effectively improving image imaging quality, increasing the utilization of data information, increasing the reliability of target detection and recognition, and improving the robustness of the system. [0003] At present, image fusion has considerable...
