  4. Firstly, while the nominal model is used, the filtering effect is very good. secondly, when the system model is n ' t definite, the filtered heading angle and rudder angle are steady in the error range. finally, when the complicated nonlinear wave model replaces the linear wave model, the filtering effect is also steady, and the estimate precision is high

    首先，模擬是在名義模型的情況下進行的，此時h _濾波器的濾波效果很好；其次，我們在系統模型具有攝動的情況下進行模擬，此時經h _濾波器濾波后的航向輸出和舵令輸出基本能夠達到穩定；最後，我們採用較復雜的非線性海浪模型代替線性海浪模型進行模擬， h _濾波器的濾波效果也是比較穩定的，並且估計精度較高。
  5. Shiphandling simulator is a device that can partly imitate the true environment at sea ， and is specially designed to satisfy marine education and trains and maritime research etc. one of its key techniques is to create the virtual environment at sea ， and the terrain is its important component. according to the needs of the real time visual display of the shiphandling simulator ， this paper analyses the requirements of the geometry precision of the important islands and background hills which are within the ships ' visible scope ， and brings forward the modeling methods of the hill ' s pileup and the hill ' s silhouette edges based on contour lines. it also presents the definition of error that the hill ' s silhouette edges graph has been given and the effective scope of application ， and firstly established the error criterion of terrain model that is built in shiphandling simulator. with these two kinds of method ， the size of data storage can be minimized greatly ， and the requirements of high update rate and geometry precision for the real time visual display of the shiphandling simulator can be satisfied

    船舶操縱模擬器是一種能夠部分模仿海上真實情況，專門為滿足航海教育與培訓、航海技術研究等目的而設計研製的裝置，其核心技術之一是海上視景模擬，而地形地貌是海上視景中的重要組成部分.根據船舶操縱模擬器實時視景顯示的需要，在分析航行船舶對可視范圍內重要島嶼與背景山脈的幾何精度要求的基礎上，提出了基於等高線的山形堆積建模和山形輪廓建模方法，並給出了山形輪廓圖形的誤差定義、有效適用范圍，以及船舶操縱模擬器中地形建模的誤差準則，該方法生成圖形的數據量較小，其圖形更新速率與幾何精度能達到船舶操縱模擬器實時視景顯示的要求
