Acquisition probability estimation model of density correlation scene matching system

The definition of scene navigability is set force, and acquisition probability is regarded as an important mark of scene navigability. The preprocessed reference map and additional noise are supposed as independent random field with zero mean. An estimation of acquisition probability on Cross Correlation Scene Matching Systems is derived by analyzing context and statistics characteristic of reference image. Many experiments with satellite images demonstrate the validity of this proposed acquisition probability model, which provides a theoretical and practical basis for design of self-guided systems using scene matching.
