摘　　要：遥感相机内方位元素的在轨标定对遥感图像的定位和测量具有重要意义。利用线阵推扫传感器构像模型,提出了一种对CBERS-02B星HR相机内方位元素进行在轨标定的方法。该方法以内方位元素和姿态角为未知参数,建立地面控制点和相应像点的共线方程组,通过解算共线方程组获得内方位元素。实验证明,用该方法对内方位元素进行在轨标定,具有很好的稳定性和精度。The on-orbit calibration of remote sensing camera is very important for the orientation and surveying of remote sensing image. A method for the on-orbit calibration of CBERS02B-HR camera interior orientation is studied with linear array push-broom sensor imaging model. Colinearity equations of ground control points and relevant image points are constructed, the interior orientation for this method with interior orientation and attitude angle as unkowm parameters is acquired. The results show that the interior orientation can be calibrated on-orbit by this method with good stability and precision.
