An autonomous star identification algorithm is described in this study. This algorithm iteratively determines a catalog star, the distances of which to its neighbors are similar to those of a given sensor star and its neighboring stars, until a unique match is found. In each iteration, only the catalog stars that receive sufficient votes are used in the subsequent steps. We also develop a useful probabilistic...
In order to obtain much better camera calibration accuracy, the last and important step is the on-whole optimization of all the intrinsic and extrinsic parameters. However, almost no concrete or performable methods are given so far. And only the principle is given that the RMS error should be the minimum, but there are no detailed realization steps. Therefore, a concrete and performable nonlinear...
