Internal Error Compensation Method Based on High-Frequency Angular Displacement for High-Resolution Optical Satellite Images
In order to address the critical compensation issue for attitude jitter in high-resolution (HR) images, a steady-state imaging model based on high-frequency angular displacement is proposed to detect attitude jitter and internal geometric accuracy compensation of HR satellite, and the accuracy of geometric calibration field is validated using digital orthogragh images/digital elevation model reference data. In the case of HR optical satellite launched in 2015, three experiments are carried out as follows: platform jitter detection, convergence analysis of attitude processing filter, and verification of jitter compensating effect. The compensation results show that the proposed platform jitter compensation model can effectively improve the imaging quality, and the internal geometric accuracy of jitter image reaches 1.5 pixel after compensation.
