Abstract

The invention discloses a data intensive computing-based remote sensing image preprocessing system. Around the problem of remote sensing data automation and business preprocessing, various remote sensing algorithm models are organized to form workflow for finishing business processing of remote sensing data, and adaptive workflow is flexibly established for different remote sensing data. A ''5-parallelism and 1-acceleration'' computing system is formed through task parallelism, data parallelism, algorithm parallelism, multi-machine parallelism, multi-thread parallelism and GPU acceleration in combination with a computing environment, so that production time of remote sensing image processing is shortened. According to the data intensive computing-based remote sensing image preprocessing system, a massive scale of various remote sensing data can be processed quickly in real time, so that the production efficiency is greatly improved while the processing precision is ensured.

Description

technical field [0001] The invention relates to the field of remote sensing data processing, in particular to a data-intensive computing remote sensing image preprocessing system. Background technique [0002] With the continuous development of aviation and remote sensing technology, remote sensing data is growing at the rate of terabits (TB), and the speed of data processing is generally slow. The timeliness of the existing manual operation methods can no longer meet the needs of daily scientific research and production activities. Require. Due to the large number of sensors and different algorithms for different types of data processing, the data-intensive computing characteristics of the processing link are becoming more and more prominent. It is necessary to combine algorithms independently of the data processing process to reduce system complexity. Aiming at these problems, remote sensing data processing needs to design a reliable semi-automatic production model and im...
