三维地形匹配性能的一种快速估计方法
A Fast Performance Evaluation Method for 3 D Terrain Matching
摘要
Abstract
A fast matching performance evaluation method is proposed for three-dimensional terrain matc-hing systems with small-amplitude undulation. The definition of performance indicators for terrain matc-hing is put forward at first. Eight-connected field is then employed to construct the multi-resolution fea-ture vectors. Multi-resolution Gaussian Markov random field is used to model the relationship between ter-rain features and the matching performance. During the procedure of feature extraction,the reference map is divided into several rectangle blocks and both the neighborhood relationship and multi-resolution charac-teristics are utilized. Learning and testing equations are introduced and therewith the analytic solutions of estimation values for performance indicators are obtained by exploring maximum a posteriori criterion. Fi-nally,it is validated that the new proposed method has better performance in terms of computing complexity and localization bias based on the ground truth sample data.关键词
