AI Technical Summary

Problems solved by technology

For tasks that require quick response, it cannot meet the task requirements
For example, fire detection or battlefield situation awareness in a military context requires immediate response based on image processing results. Satellite-to-earth data transmission needs to take up a lot of transmission time, which affects the effectiveness of the task.

Description

technical field [0001] The invention relates to the technical field of satellite imaging, in particular to a space-based intelligent imaging system. Background technique [0002] With the development of aerospace payload technology, the detection data acquired by various high-resolution detection instruments has increased significantly, while the development of on-board data processing capabilities and satellite-ground communication capabilities has lagged behind. In addition, the data acquired by the payload contains a lot of invalid data, resulting in a waste of space-based data storage, management, and transmission resources. Due to limited space-borne computing capabilities, the existing space-based imaging methods cannot perform effective calculations on the satellite, and only perform simple calculations or no calculations, and transmit the data to the ground for processing. [0003] Due to the limitation of on-board computing power, effective calculations cannot be p...
