摘要: 玉兔号安装了一对全景相机全景相机使用的镜头设计为视场小的长焦距镜头这种镜头的光线束入射角较小若采用传统的透视投影模型进行相机检校可能会造成法方程式系数矩阵的病态 针对这一特点本文提出一种基于正交变换模型的相机检校方法通过真实数据试验证明该方法具有很高的精度和稳定性可以用于对玉兔号月球车的全景相机进行检校Abstract: the scientific instruments on the jade rabbit include a pair of pancams desi gned with narrow fields of view and long-focus.because the li ght beams incident angle of this kind of lens is relativel y smallif a camera is calibrated by the traditional pers pective pro jection modelthe coefficientmatrix of its normal equation maybe ill -conditioned.a calibration approach based on orthogonal projection model is proposed.experimental results reveal that this approach can be used in calibration ofthe jade rabbit pancams with hi gh accurac y and stabilit y.
