Abstract

The invention discloses a remote sensing image super-resolution reconstruction method based on multi-angle linear array CCD sensors. The remote sensing image super-resolution reconstruction method comprises the steps of arranging the linear array CCD sensors according to specific modes and different angles and catching two-dimensional image information in a target area; obtaining high-resolution images from low-resolution images obtained from multiple linear array CCD sensors according to relative arrangement position relationships between the linear array CCD sensors and correlations and differences between scene information caught by the linear array CCD sensors. According to the remote sensing image super-resolution reconstruction method based on the multi-angle linear array CCD sensors, the feature that a single row pixels of linear array CCD is much higher than that of area array CCD in a one dimensional space, the regional image of the same target at different angles are obtained through different angle arrangement of the multiple linear array CCD, the correlations and differences of each image are utilized, the high-resolution images are obtained, and the super-resolution reconstruction of aerial images, satellite remote sensing images and the like is applicable; the proposed super-resolution reconstruction method is simple to realize, the reconstruction effect is precise, and the practical application is easy.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a remote sensing image super-resolution reconstruction method based on a multi-angle linear array CCD sensor. Background technique [0002] In aerospace, remote sensing cameras are used as information acquisition devices, which can capture the target area of ​​the earth and form a two-dimensional image map of the area. With the development of CCD technology, traditional film cameras have been replaced by CCD sensors. CCD sensors can be divided into two types: linear array CCD sensors and area array CCDs. Among them, the area array CCD can be used to directly obtain two-dimensional image information, but the total number of pixels is large, while the number of pixels in a single row is small, and the frame rate is limited. The total number of pixels of the linear array CCD sensor is small, but all of them are distributed in one-dimensional space, so the number of pixe...
