Abstract
The Matlab Symbolic Computation approach is proposed for estimating information in vision navigation analysis. The rank, eigenvalue and eigenvector of optimal error covariance matrix of the six-degree-of-freedom variables are calculated. And some conclusions about the observability of vision navigation information are obtained. By the simulation, the process of theoretical derivation in reference [2] is simplified and the correctness of the conclusion in reference [2] is verified. The method presented here is of practical value.
