摘要
为了解决导航用数字地图分辨率选取不明的问题,构建了多地形水下数字地图,基于经典TERCOM匹配算法,对数字地图分辨率与匹配误差的定量关系进行了仿真及多项式回归分析。结果表明,不同特征地形对适宜分辨率的要求不同,小起伏区和大起伏区适宜分辨率分别为12 m和25 m,数字地图分辨率与匹配误差关系近似服从多次曲线变化规律。
In order to solve the problem that the digital map resolution for navigation is not clear,underwater digital maps of different terrain were built and based on the classical TERCOM matching algorithm,the simulation and polynomial regression analysis of the quantitative relationship between the digital map resolution of different terrain and matching error were carried out.The results show that the requirements of different characteristic terrain for the appropriate resolution are different.The requirements of small fluctuation area and large fluctuation area are about 12 m and 25 m respectively and the relationship between the digital map resolution of different terrain and matching error appropriately obeys the law of polynomial curve.
