ABSTRACT:
A method for navigation and updating of navigation for aircraft uses range image processing and a reference store, segmentizing the range image data are segmentized in order to obtain a particular pattern of type features for purposes of classifying particular types of objects across which the craft flies; extracting particular signature features including localized elevational jumps and determining the position of the craft by correlating a plurality of features and their spatial orientation to each other as extracted with corresponding stored reference information in order to provide a maximum fit that is indicative of deviation of the flight from a flight path as identified by the reference information.
