Abstract

The invention discloses a registration method between multi / hyperspectral remote sensing image bands. Through feature extraction and calculation analysis, the gray features of different bands and image space features are combined to solve the registration between multi / hyperspectral image bands. The problem is used for preprocessing of multispectral image color synthesis and hyperspectral image data cube synthesis, thereby improving the universality of multi / hyperspectral remote sensing data.

Description

technical field [0001] The invention relates to the technical field of remote sensing data processing, in particular to a multi- / hyperspectral remote sensing image band registration method. Background technique [0002] With the increasing development of remote sensing earth observation, multi / hyperspectral image processing has become one of the hotspots in imaging technology and application fields in recent years. As an important means of remote sensing earth observation, multi / hyperspectral remote sensing Fine-grained segmentation capabilities are promoted. For remote sensing images, image registration is an essential preprocessing step in image processing operations such as image geometric correction, image stitching, color synthesis, and super-resolution reconstruction. It is also an important step for subsequent data applications of multi / hyperspectral remote sensing images. Early preparation. [0003] Generally speaking, the registration error of high-resolution remo...
