Method for parallel processing of remote sensing imagery data

Abstract

The invention provides a method for parallel processing of remote sensing imagery data. The method is based on a plurality of terminals connected through an Ethernet; at least one terminal in the plurality of terminals is provided with a task management and scheduling unit, and each terminal is provided with a computing unit. The method comprises the steps as follows: a first terminal in the plurality of terminals receives a remote image processing task; the computing unit of the first terminal resolves the remote sensing image processing task into a plurality of sub-tasks, encapsulates and submits the sub-tasks to the second terminal provided with the task management and scheduling unit; the task management and scheduling unit of the terminal issues the sub-tasks between the computing units of the plurality of terminals, and the computing units of the plurality of terminals respectively carry out the issued sub-tasks. In the invention, the computing resources of the computer used by different interpretation personnel are fully utilized, and the demand of the remote sensing image data processing on hardware of the computer is reduced.

In the face of massive remote sensing image data, the efficiency of remote sensing image data processing is a key issue that must be solved, otherwise it will become a bottleneck restricting the application of key technologies in actual systems. Therefore, how to improve the processing efficiency of remote sensing image processing system It has become a hot topic of research, and it is also a difficult problem with great challenges

[0007] As can be seen from the parallel processing method of remote sensing image data in the prior art, it has the following technical defects: (1) high requirements for hardware configuration, requiring a high-performance cluster computer dedicated to computing; (2) development of remote sensing image processing functions requires Following a specific protocol is not conducive to the transplantation and integration of algorithms on different platforms; (3) The large size of remote sensing images is not considered, and there are often exceptions of insufficient memory
