| 摘 要： | 嫦娥-3号月面巡视探测器安装了一对导航相机、一对全景相机和一对避障相机,对这3对立体相机的检校是实施月面巡视探测器导航定位和地形恢复的基础。通过建立高精度的控制场,采用附有约束条件的间接平差方法,对嫦娥-3号月面巡视探测器的立体相机进行高精度的检校。试验表明,该方法能够提高相机检校的精度和稳定性。

| Abstract: | Calibration of the stereo-camera system is the basis of lunar rover navigation and cartography. The scientific instruments on the Chang'e-3 lunar rover include a Navcam, Pancam, and Hazcam, Self-calibration bundle adjustment with restrictive constraints based on high accuracy control field was employed to calibrate the stereo-camera system of Chang'e-3 lunar rover. The experimental results reveal that this approach can improve the accuracy and stability of calibration. |
