Secondly, an algorithm of image processing is introduced which can detect horizon of airfield and edges of runway commendably. and then, based on work of former researchers, it is developed which is a software system of uav ’ s autonomous landing image processing and parameter - obtained. a corresponding simulation experiment has been done making use of this software
本文所研究的跑道的識別和跟蹤、地平線和跑道邊緣的提取、無人機飛行參數求解構成了基於計算機視覺的無人機自主著陸方法研究的主要內容，為實現相應的工程應用打下了基礎，具有重要的意義。 -
First, the standard errors computed under the assumptionthat the error term is independent identical distribution will be biased. second, theassumption of independence is unlikely to satisfied. in the panel data analysis modelwith hierarchical structure, hierarchical effects, nested effects, time effects are seted. then the dissertation deduced parameter estimation and hypothesis test statistic andits probability distribution and analyze the hierarchical panel data set : eastern china, central china and western china are the top level, and the prc ’ s province, cities, and autonomous regions are bottom level
然後針對目前面板數據分析過程中存在的兩方面問題，即一方面在利用面板數據模型進行分析時，標準誤差的計算是基於誤差項相互獨立並且同分佈的假設，如果誤差項是相關的將會造成估計有偏的後果;另一方面關于獨立性這一假設本身就難以滿足;提出多層嵌套面板數據模型，設定了層效應、嵌套效應以及時間效應參數，研究了多層嵌套模型的參數估計量和假設檢驗統計量及其分佈。 -
Spacecrafts are working in the space environment, which is full of sorts of physical mediums. and these mediums will impact on the altitude movement of spacecraft. spacecraft attitude control during propulsive maneuvers is complicated due to several factors as listed below : ( i ) nonlinear dynamics with time delays, ( ii ) modeling and parameter uncertainties, ( iii ) flexible modes due to fuel sloshing and appendages, ( vi ) constraints on propulsive force and torque inputs, ( v ) constraints on acceptable angular rates and attitude, ( iv ) autonomous reconfiguration requirements under failure conditions
飛行器是在一定的空間環境中飛行，而空間環境中充滿著各種物理介質，對飛行器的姿態運動產生不同程度的影響，所以空間飛行器的姿態控制相當復雜，它受到如下因素的制約： （ ? ）帶時延的非線性動態特性（ ? ）模型和參數的不確定性（ ? ）燃料的激蕩性以及燃料消耗所引起飛行器的質量變化（ ? ）推力和輸入力矩的約束性（ ? ）額定角速度約束和姿態約束（ ? ）在故障發生的情況下自動重新配置的必要性。
