摘要

针对质点滤波(point-massfilter,PMF)算法应用中会出现概率密度函数发生除零现象以及出现匹配野值等问题,首先从算法原理上分析了概率密度函数发生除零的原因并提出了处理方法,然后将判断准则引入PMF算法中来防止出现匹配野值,并在搜索区域不同分辨率的条件下,对判断准则的取值进行了分析,得出了最佳值。最后以此为基础对改进的PMF算法在水下地形匹配导航中的地形适应性进行了仿真分析,结果表明该算法具有较好的可行性和适应性。

Abstract

Due to probability density function dividing zero and appearing matching outliers of point-mass filter algorithm in application, firstly, the reason of dividing zero was analyzed from algorithm principle and the solution was proposed. Then judgment criterion was introduced to prevent matching outliers, the best value was got through analyzing the value of judgment criterion under different resolution in the search area. Finally, the improved PMF algorithm was simulated to analyze terrain adaptability in underwater terrain matching navigation based on these, result shows the algorithm has a good feasibility and adaptability.

Key words： PMF algorithm; terrain matching; terrain adaptability; navigation
