Abstract

The invention provides an earth surface radiation product repairing method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining an earth surface coverage classification product and an initial earth surface radiation product of a target region; extracting abnormal pixels in the initial earth surface radiation product and performing uniform assignment to obtain a new earth surface radiation product; in the new earth surface radiation products, traversing and searching invalid value pixel points, and determining a plurality of nearest similar pixel points corresponding to the invalid value pixel points in the earth surface coverage classification products; and repairing invalid value pixel points based on the average value of the spectral data corresponding to the plurality of closest similar pixel points. According to the surface radiation product restoration method and device, the electronic equipment and the storage medium provided by the invention, the defect of data missing or data abnormity of a surface radiation product in the prior art can be solved, and missing data and abnormal data in the surface radiation product in a global large-area range can be restored.

Description

technical field [0001] The invention relates to the technical field of remote sensing image processing, in particular to a surface radiation product repairing method, device, electronic equipment and storage medium. Background technique [0002] Surface radiation products are an important basis for remote sensing macro monitoring. However, the surface radiation products are often unable to obtain the surface radiation of the pixel value due to cloud and fog and the remote sensor itself. In order to ensure the comprehensiveness and integrity of remote sensing monitoring, data restoration needs to be carried out. One of the current data restoration methods is to restore data based on the spatial correlation of the data itself. This method is only suitable for small-scale data loss. Radiation data products or microwave data are used as auxiliary data to carry out restoration, but at present this method is mainly a local theoretical research. Because it is difficult to obtain g...
