Quick processing method and system for high-resolution remote sensing image

Abstract

The invention provides a quick processing method and a quick processing system for a high-resolution remote sensing image and relates to the field of sensing image processing. The quick processing method comprises the steps that S1, an image and a DEM (digital elevation model) are referred to from a remote sensing image database according to the range of a to-be-corrected image; S2, a control point is matched through an automatic matching method according to the image and the DEM of the remote sensing image; S3, the to-be-corrected image is processed according to the control point, and the remote sensing image is dynamically generated; S4, the dynamically-generated remote sensing image is previewed in real time; S5, if the generated remote sensing image is qualified, the remote sensing image is generated; and if the generated remote sensing is not qualified, the to-be-corrected image is processed again in the step S3. The invention also provides a quick processing system for the high-resolution remote sensing image. The quick processing method and the quick processing system for the high-resolution remote sensing image solve the problems of mass processing and high-efficiency processing of information of a remote sensing satellite, promote the application integration of remote sensing data result products, lower the technical difficulty and play an important role in applying remote sensing image data in various industries and the overall building of a digital city.

Description

technical field [0001] The invention relates to the technical field of remote sensing image processing, in particular to a method and system for fast processing of high-resolution remote sensing images. Background technique [0002] At present, the mainstream satellites at home and abroad are mainly from the United States, France, the European Space Agency, Germany, China, Japan, India and other countries or organizations. The sensors carried by the satellites are different, and the resolution ranges from 0.5m to 100000m. The satellite acquisition band span Not one, the efficient processing of massive data has always been in a bottleneck state, first of all, how to design a method that can be compatible with various mainstream satellite image data is a huge and difficult systematic problem; second, in the face of massive remote sensing data, for different industries , the business needs of different fields, how to efficiently process images while meeting the different needs ...
