地形轮廓匹配 | | 2. | This is a new way that introduces the technology of image processing to terrain matching
这是一种将图像处理技术应用到地形轮廓匹配的全新思路。 | | 3. | This paper also discusses theories , characters , applications of the three following algorithms of terrain matching system : terrain contour matching ( tercom ) , terrain - aided inertial navigation system , wavelet transform , the simulation results are provided
论文先后讨论了地形轮廓匹配算法、卡尔曼滤波地形辅助导航算法、小波分层算法的原理、特点、适用范围，做了仿真研究，比较了它们的匹配性能和相关特点。 | | 4. | Generally speaking , the algorithm of terrain contour matching is adapted to be used in cruise missiles which made fight path prior for that this algorithm is not a real - time system for it makes use of historical terrain data . while kalman filter algorithm is a real - time , rapid calculation system . which is appropriate for pilot or pilotless aircraft
得出，地形轮廓匹配算法使用历史地形数据，实时性差，比较适合事先规划好航迹的导弹使用：卡尔曼滤波的方法有较好的实时性，计算速度快，很适合有人无人驾驶飞机的机动飞行要求；小波分层只是对地形信息做了高低频分解，其本质还是相似性度量算法，但它有效的降低了匹配算法的计算量。 | | 5. | In this paper , the main research works are as follows : 1 ) survey and analysis previous work in auv navigation and summarize : as the cumulate error , the dead - reckoning and inertial navigation systems ca n ' t be used without other modified system ; the acoustic navigation system is used only in small range , and is very expensive . 2 ) two important approaches in geophysical navigation techniques are summarized , one is terrain contour based navigation , this approach is investigated keystone today ; the other is image based navigation , due to no perfect image sensors and image seabed map , this approach has seldom been practised . 3 ) two important terrain contour based navigation algorithms has been applied to auv , one is match algorithm - based terrain contour match ( tercom ) ; the other is kalman filter - based sandia inertia terrain - aided navigation ( sitan )
主要研究内容包括：一、总结分析了当前水下导航的常用方法和不足之处，指出基于航位推算的导航方法，存在着最大的问题就是导航误差的积累问题，如果没有修正系统，这种方法很难满足使用要求；其次指出基于声学的导航方法，造价昂贵，导航范围有限，难以满足自主水下航行器大范围导航的需求；二、总结了当前水下地形辅助导航的主要技术路线，一是基于地形高程的匹配方法，这是当前研究的重点；二是基于地形图像的匹配方法，由于缺乏良好的图像传感器，和可用的海底图像地图，目前这种方法还有待研究发展；三、将两种地形高程匹配的常用方法应用到自主水下航行器上：以相关算法为前提的地形轮廓匹配( tercom )方法和以卡尔曼滤波为基础的桑迪亚惯性地形辅助导航( sitan )方法，前者算法简单可靠，但是导航精度不高，后者虽然精度比较高，但存在着算法较为复杂、有可能发散和出现奇异值等问题。 |
