| 摘 要： | 由于空间机器人需要在线标定以及星载计算机计算能力的限制,对相机标定方法提出了特殊的要求。为此,该文对目前2种相机标定方法(线性标定和非线性标定)进行理论分析和推导,并结合实验结果对它们的实时性和精确性进行比较,从而确定在空间机器人中适用的相机标定方法。

| Abstract: | Considering that space robots need calibration online and the computing capability of the computers on satellites is limited, there are some special requirements for camera calibration methods. In this paper,the two present methods, i.e. linear calibration and nonlinear calibration,are analyzed theoretically,and based on the results of an experiment,a comparison between the two calibration methods is made in the respects of real-time calculation and accuracy. It is considered that the nonlinear calibration method is comparatively suitable for the cameras on space robots. |
