摘要: 介绍了测绘相机立方镜与星敏感器立方镜间坐标系转换关系的标定方法。采用4台自准直经纬仪分别对两个立方镜进行准直测量,建立立方镜坐标系,并推导了基于准直测量角度的立方镜坐标系的旋转矩阵公式;利用经纬仪间短边互瞄方法实现两个立方镜间姿态的传递。标定试验表明,该方法可以标定出两立方镜坐标轴间夹角以及测绘相机间的姿态关系,满足了相机研制要求。

Abstract: One method for calibrating the transformation matrix of cubic prism coordinate system between stereo mapping camera and star sensor was adopted. Autocollimation on two cubic prisms was finished using 4 theodolites. After that, the cubic prism coordinate system was set up. And the detailed equations of rotation matrix were deduced too. The attitude between two cubic prisms was calibrated by azimuth transmission. Tests indicate that the calibration error of angle between two cubic prism coordinate system axes is less than 1.5″(1δ). The error of final attitude calibration of the stereo mapping camera is less than 5″(1δ).
