Problems solved by technology

[0003] However, at present, the multiple cameras carried by my country's environment-1 and Gaofen-1 satellites have a large width, which makes the overlapping range of multiple camera images small, and it is difficult to quickly obtain high-resolution images using conventional fusion methods.

Abstract

The invention discloses a multi-camera image mosaic method and device based on the same satellite platform, which can quickly mosaic the multiple camera images of the same satellite platform and has a wide application range. The method includes: acquiring a plurality of camera images to be mosaicked on the same satellite platform; for the two camera images to be mosaicked currently, selecting one camera image from the two camera images as a reference image, and selecting the other one as a to-be-corrected image image; calculate the spatial position deviation and color deviation between the reference image and the image to be corrected; use the spatial position deviation and color deviation to correct the to-be-corrected image; compare the reference image with the corrected image The images to be corrected are stitched together.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to a multi-camera image mosaic method and device based on the same satellite platform. Background technique [0002] Mosaic color uniformity of remote sensing images has always been the basis and hotspot of remote sensing image research, especially for optical multispectral data. In the existing literature, scholars have conducted various researches on the method of multispectral image mosaic uniformity, and also created many method models, such as histogram matching, automatic stitching line generation, maximum gain method model, feathering and other methods. Conventional mosaicking requires high-precision geometric correction of images, and the overlap between images to be mosaiced should not be too small. [0003] However, at present, the multiple cameras carried by my country's environment-1 and Gaofen-1 satellites have a large width, which makes the overlapping range of...
