| 摘 要： | 为了对星敏感器的非线性畸变进行在轨检校,本文提出了一种非参数化的检校方法,该方法以B样条格网的形式表达非线性畸变,不需要预先估计一个参数化的畸变模型,从而可以处理任何形式的畸变。针对星敏感器不同模式畸变的仿真实验表明,本文提出的方法有效、可靠并且具有鲁棒性。

| Abstract: | Aiming at on-orbit calibration to non-linear distortion of star tracker, we proposed a non-parametric calibration ap-proach, in which the non-linear distortion is expressed in form of a B-spline gird regardless of the patterns of distortion. The cali-bration needs no estimation on parameterization of a pre-designed model, and can treat any type of distortion. Simulation experiments on different patterns of star tracker' s non-linear distortions demonstrated that the proposed method is effective, reliable, and robust. |
