Abstract

The invention relates to a method and a device for processing a remote sensing image. The method comprises the following steps: obtaining the largest data processing amount of a plurality of subnodes in the grid; segmenting the remote sensing imaged into a plurality of remote sensing subimages according to the largest data processing amount; and sending the remote sensing subimages to the subnodes and then leading the subnodes to respectively process the received remote sensing subimages. The method and the device for processing the remote sensing image lead the remote sensing image to be segmented into the remote sensing subimages according to the largest data processing amount of the subnodes in the grid, therefore, the subnodes in the grid can parallelly process the remote sensing subimages according to the processing capacity of the subnodes, thus increasing the processing speed of the remote sensing image.

Description

technical field [0001] The invention relates to remote sensing technology, in particular to a remote sensing image processing method and device based on a distributed collaborative manner. Background technique [0002] At present, remote sensing technology has been widely used, for example: in weather forecasting, land census, crop yield estimation, forest survey, geological prospecting, ocean forecasting, environmental protection, disaster monitoring, urban planning and map surveying, etc. Processing can enable better application of remote sensing technology, and can realize the prediction of natural disasters in advance, so as to minimize losses; it can also realize timely weather forecasting; it can also monitor major projects in a timely manner, thus improving the speed of remote sensing data processing has become an increasingly prominent problem. [0003] With the development of information technology and sensor technology, the spatial resolution, spectral resolution,...
