摘要
影像匹配算法的有效性依赖于对一些共同的基本问题的解决,即选择正确的匹配基元,寻找基元间的本质属性,制定相应的匹配准则(约束条件),采用合理的匹配策略,设计良好的算法结构等等。首先分析了3种常用匹配基元的特点并提出匹配基元的选取依据,接着归纳出了5种常用的匹配准则,对分层匹配、全局搜索等4种匹配策略进行了讨论,最后设计了一种3个阶段、9个步骤的影像匹配算法结构。实验结果表明:匹配效果良好,对这些基本问题的研究有利于建立通用的影像算法模型,设计更高效的影像匹配算法。
The validity of photography matching algorithms depends on the resolving of several essential problems,such as the selection of right matching elements,searching the substaintial properties among the elements,the establishment of matching constraints,the adoption of proper matching tactic,the design of sound algorithm structure and so on.Firstly,analyses the characters of the 3 common matching elements and puts on the accordance of choosing elements.Secondly,5 matching constraints are summarized and several matching tactics are discussed.Lastly,a matching algorithm that consisted of 3 stages and 9 steps,is designed.The experiment result shows that the matching result is good,and the resolving of such essential problems will help constituting universal photography matching model and designing more proficient matching algorithms.
