High-resolution satellite image data batch preprocessing method

Abstract

The invention relates to a high-resolution satellite image data batch preprocessing method, and aims to solve the problems of many steps and long processing time in a high-resolution satellite data preprocessing process. Orthographic correction, radiometric calibration, image registration, atmospheric correction, region-of-interest extraction and other preprocessing operations are sequentially performed on the satellite remote sensing data image, so that the preprocessed region-of-interest high-resolution satellite image can be automatically obtained in batches, and the preprocessing of the satellite remote sensing data image can be realized more simply and quickly; and the decision of major events can be carried out better and more quickly.

Description

technical field [0001] The invention relates to a method for batch preprocessing of high-resolution satellite image data, which belongs to the technical field. Background technique [0002] my country's remote sensing satellites Gaofen-1 (GF-1) and Gaofen-2 (GF-2) performed well during the on-orbit test. Precision agricultural information services, disaster prevention and post-disaster rescue provide strong support for the strategic needs of national economic construction and social development. [0003] Remote sensing data preprocessing is the process of using a computer image processing system to perform a series of operations on pixels in remote sensing data, and remote sensing data images contain a lot of information. Limited by the size of the medium, traditional analog data images cannot fully express the information, and it is difficult to further process the information. Only after digitization can the information be analyzed and processed effectively. The conventio...

AI Technical Summary

Problems solved by technology

So far, there is still no research on batch preprocessing of GF-1 and GF-2 data in my country. In order to realize the image preprocessing of satellite remote sensing data more concisely and quickly, and greatly improve labor productivity, batch preprocessing is particularly important. important

At present, the preprocessing of GF-1 and GF-2 satellite data is still in the basic stage of remote sensing data, and batch processing of GF-1 and GF-2 remote sensing data cannot be realized, so it will consume a lot of time in practical application , especially in disaster decision-making, forest fires, etc.
