均匀设计用于地形特征与匹配性能关系的研究

分析地形特征因素与地形匹配性能的理论关系，并进行大量实验，用多元二次回归模型分析实验结果，得到其实际关系．实验中采用均匀设计法，构造U28（286）表，设计实验参数，挑选实验对象，从而减少了实验次数．实验所得的实际关系与理论分析结果相吻合．

Research on the Relations between Terrain Features and Performance of Terrain Registration Using Even Experiment Design

The relation between terrain features and terrain registration algorithm is analyzedtheoretically and experimentally. Terrain features that will affect the performance of terrain registration arechosen, and the theoretical relation between them and the performance of terrain registrationanalyzed. A lot of experiments are undertaken, their results are studied by multi-variable quadraticregressive model, and the realistic relation is obtained. Even experiment design is used in theexperiments, and the times of the experiment are reduced to equal to the numbers of standards of theexperiment while not affecting the reliability of result. The concrete design method of even design table isrepresented, and the discrepancy of even design is analyzed. A U,,(28') table is offered for itspractical application, whose discrepancy is least. The results of the experiment are analyzed by multi--variable quadratic regressive model. There is a very bit between the relation given from the experimentand the one from theoretic analysis.
