The invention provides a method and a device for information loss reconstruction of a remote sensing image, wherein the method comprises the steps of acquiring a reference image in a same area of an information loss remote sensing image; according to spatial similarity between the information loss remote sensing image and the reference image, constructing a linear relation between an output image and the reference image, wherein the output image is obtained through performing information loss reconstruction on the information loss remote sensing image; constructing an edge weighted cost function of the linear relation between the output image and the reference image, performing parameter solving on the edge weighted cost function, calculating the average value of each solved parameter; and according to the solved linear relation among the average value of each parameter, the output image and the reference image, performing information loss reconstruction on the information loss remote sensing image, and obtaining the output image obtained after reconstruction. The method and the device can settle information loss problems such as bad pixel, bad strip and cloud shielding caused by restriction of factors such as weather and sensor damage in an acquisition process.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a remote sensing image information missing reconstruction method and device. Background technique [0002] Remote sensing image data provides a large amount of information on ground objects, which is beneficial to various applications such as agriculture, forestry, environmental planning and so on. However, the development of remote sensing is still subject to many restrictions. The main reason is that the process of obtaining remote sensing images will be interfered by many factors, such as cloud interference, damage to the remote sensing sensor itself, etc., which will cause the obtained remote sensing images to have bands. Noise or dead pixels, or a large area of clouds will appear, which greatly affects the application of remote sensing in various fields. [0003] At present, the main method to solve the problem of missing remote sensing data information includes ...
