Description

technical field [0001] The invention relates to the field of satellite technology, in particular to a spaceborne image processing device and a spaceborne image processing and decision-making platform. Background technique [0002] As the detection capability of space-borne imaging equipment becomes stronger and stronger, the data of on-board images increases exponentially. However, the real-time processing capability of on-board images cannot keep up with the pace of data growth. [0003] At present, the traditional on-board data processing method is to transmit the image data obtained from the satellite to the ground through the satellite-ground link, and the ground analyzes and calculates the received image data, and further adjusts the payload imaging strategy. However, the above-mentioned on-board data processing method that mainly uses ground analysis and interpretation, supplemented by on-board data processing to complete on-board image data processing and analysis has...
