摘要

卫星在轨运行过程中

载荷姿态不可避免受到平台抖动、传感器热形变等安装误差因素一定程度的影响

导致图像定位精度下降。针对该问题

通过建立相应的安装误差状态转移模型和基于特征点的观测模型、采用扩展卡尔曼滤波（EKF）

实现对安装误差的实时估计。采用基于特征点的天基传感器姿态实时校正方法

数学仿真表明:该方法能够实现姿态实时校正

且性能稳定

可有效提高图像定位精度。

Abstract

Payload attitude is inevitably affected by installation error factors such as platform jitter

and sensor thermal deformation error

to some extent

when satellite is in orbiting

that leads to lower precision of image localization. A real-time attitude calibration algorithm for space-based optical sensor based on feature points is presented. Firstly

the state model of the installation error and observation model based on feature points are established. Secondly

an EKF is used to achieve real-time estimation of installation error. Simulation results show that the algorithm can achieve real-time attitude calibration and has stable performance

and can effectively improve the precision of image localization.
