Abstract

The invention provides a multiplexing self-repairing image processing system for spaceflight. The multiplexing self-repairing image processing system comprises a main control module, a data source module and a processing and analyzing module, wherein the main control module comprises a control unit, a data processing unit and a time-sequence judging unit; the data source module comprises a plurality of cameras; the processing and analyzing module comprises a plurality of data processing and analyzing units; the time-sequence judging unit judges whether the current data processing and analyzing unit has a failure or not through the time sequence in which the data processing unit receives compressed image data sent by the data processing and analyzing units, and performs initialization, and besides, the data processing and analyzing units calculate DN values of the image data so as to regulate the image data quality of the cameras. The multiplexing self-repairing image processing system disclosed by the invention supports the input of different formats of image data and can be adapted to the camera application of various satellite interfaces; the multiplexing self-repairing image processing system can automatically complete the detection and repair of failures, so that working efficiency and reliability of the image processing system are improved.

Description

technical field [0001] The invention relates to an image processing system suitable for aerospace, in particular to a multiplexing self-repairing image processing system suitable for aerospace. Background technique [0002] At present, there are various image processing technologies for CCD and CMOS in the aerospace field, while the traditional image processing system for aerospace applications is a single input and output system, which does not support parallel processing of multiple different image data, and the integration degree is low. Failures cannot be automatically detected and repaired when a failure occurs. [0003] The on-orbit image processing and simulation analysis method of aerospace optical remote sensors developed by Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences can realize on-orbit automatic focusing and correction of a single optical remote sensor. Foreign Intelcel America Inc. provides a method for reading and wri...
