Paper Abstract

A novel contour-based 3D terrain matching method is presented in this paper. In the method, Iso-Elevation Contour Map (IECM), a compact feature-based representation, is proposed to represent the reference DEM and recovered DEM(REM) from real-time data to convert 3D terrain matching to contour-based matching. In the contour-based matching, a normalized wavelet descriptor, which is invariant to 2D rigit transformation, is employed to describe contours. A very fast contour-matching algorithm based on normalized wavelet descriptor is presented. The proposed matching method is robust and effective computation, and can achieve high location accuracy.
