Adaptive real-time processing method for remote sensing images of ground system

Abstract

The invention relates to an adaptive real-time processing method for remote sensing images of a ground system, which comprises the following steps: starting a corresponding processing program in a processing server according to the requirement of a user for the processed result level of the remote sensing images; constructing a circular queue and establishing shared memory mapping, then decompressing the received remote sensing image data, dividing the decompressed remote sensing image data into data blocks of the same size, and sequentially storing into the circular queue; sequentially carrying out real-time processing on the data blocks in the circular queue by each processing program, and generating the processed results of the remote sensing images required by the user; and storing the processed results of the remote sensing images in the processing server or storing in a customer server. The invention solves the problem of time delay among the processing links of the current ground processing system, and greatly improves the operating efficiency of the system; and with the increasing amount of remote sensing data, the requirement of processing a large amount of remote sensing information in real time can be basically met by processing the remote sensing data by the processing mode based on the invention.

Description

technical field [0001] The invention relates to an adaptive real-time processing method for remote sensing images of ground systems, and belongs to the field of remote sensing image processing. Background technique [0002] With the improvement of aerospace technology, computer technology, and communication technology, modern space remote sensing technology has also developed rapidly, gradually forming a satellite observation system with high spatial, high spectral, and high temporal resolution, with near real-time, all-weather access to various capabilities of remote sensing data. At present, in the application of earth observation data, information processing has become a bottleneck problem. Usually, only about 10% of the images received by remote sensing satellites can be processed in time for users. On the one hand, we can obtain a large amount of Earth observation data every day; on the other hand, due to the backward processing technology, a large amount of data canno...
