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. Precision Mosaic Image

Abstract

The invention discloses a multi-camera image mosaicking method and a multi-camera image mosaicking device based on a same satellite platform. The multi-camera image mosaicking method includes the steps of acquiring multiple to-be-mosaicked camera images of the same satellite platform; within two current to-be-mosaicked camera images, selecting one camera image as a reference image, and selecting the other camera image as a to-be-calibrated image; computing spatial positional deviation and color deviation between the reference image and the to-be-calibrated image; calibrating the to-be-calibrated image according to the spatial positional deviation and the color deviation; splicing the reference image and the calibrated image. The multi-camera image mosaicking method and the multi-camera image mosaicking device are capable of performing quick mosaicking on the multiple camera images of the same satellite platform and wide in application range.

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 and color matching 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 mosaicking and leveling, and have also created many method models, such as histogram matching, automatic stitching line generation, maximum gain method model, feathering and other methods. Conventional mosaic color leveling requires high-precision geometric correction of images, and the overlap between images to be mosaicked should not be too small. [0003] However, at present, the multiple cameras carried by my country's KJ-1, Gaofen-1 and other satellites have large widths, which makes th...
