Abstract

The invention discloses a splicing method of hyperspectral line array remote sensing images carried by drones. Firstly, the hyperspectral remote sensing images to be spliced ​​are collected, and feature points are selected and matched; image transformation is selected based on the matched feature points. The model performs image registration to obtain the registered image; based on the registered image, the overlapping area is feathered and color balanced, and then pixel-based mosaic is performed to obtain the spliced ​​hyperspectral image; based on the Georeferencing the spliced ​​hyperspectral image with the area array orthophoto of the above image to obtain a hyperspectral image with real geographic coordinates. The above method can solve the problem of small coverage of a single image of the UAV. While ensuring the visual effect, it can also ensure that the spectral distortion of the images before and after stitching is small, and the final stitching result has real geographic coordinates.

Description

technical field [0001] The invention relates to the technical field of remote sensing image processing, in particular to a method for splicing remote sensing images of an unmanned aerial vehicle-borne hyperspectral line array. Background technique [0002] Hyperspectral technology uses a large number of very narrow electromagnetic wave bands to obtain relevant data from objects of interest, including rich spatial, radiative and spectral information, and its most important feature and sign is the combination of spectrum and image. Frontiers of Remote Sensing Technology. Because hyperspectral remote sensing images have high spectral resolution and can provide more abundant information on the earth's surface, they have received great attention and wide application by scholars at home and abroad. Effective technical means in the fields of cartography, vegetation survey, marine remote sensing, agricultural remote sensing, atmospheric research, and environmental monitoring are pl...
