Remote sensing satellite platform control and image correction method based on flutter information

Abstract

The invention discloses a remote sensing satellite platform control and image correction method based on flutter information. The method comprises the steps of simulating satellite motion and constructing a flutter image data set, expanding data volume through data enhancement, preprocessing flutter image data, extracting image flutter information by using a ResNet algorithm, feeding back the flutter information to a satellite attitude control system for control, and guiding a Transformer model to perform image correction by using the flutter information. In order to solve the technical problem that space tasks such as high-resolution reconnaissance cannot be clearly imaged due to limitation of high-frequency low-amplitude micro-vibration of a spacecraft, satellite flutter information is solved by using a flutter image, and a satellite platform is controlled and image correction network learning is guided by using the flutter information. Therefore, a satellite flutter estimation, attitude control feedback and image correction closed-loop system is built. The invention provides a satellite flutter information estimation and attitude control information feedback based on a ResNet algorithm and a flutter image correction intelligent method based on a Transform model, and the spatial information intelligent processing capability of China is effectively improved.

Description

Technical field [0001] The present invention relates to the field of object recognition, in particular to a remote sensing satellite platform control based on flutter information and an image correction method thereof. Background [0002] In space missions, remote sensing satellite Earth observation has extremely high military and commercial value, however, subject to the impact of high frequency and low amplitude micro-vibration of spacecraft, remote sensing satellites can not be clearly imaged, thus seriously restricting the use of remote sensing images. Satellite flutter is a kind of high-frequency low-amplitude micro-vibration that is difficult to detect and correct, which effectively estimates the satellite flutter information, controls the satellite platform according to the flutter information, and finally uses the relevant algorithm to correct the distortion remote sensing image, which can effectively solve the impact of satellite flutter on the remote sensing image.
