In this paper, the method vision - based for uav autonomous landing is researched using technology of image processing, computer vision and projection geometry. the first task of computer vision - based uav autonomous landing is to recognize and track the runway using computer vision. a simple method is discussed to recognize and track the runway in the image sequences using template matching
本文的研究工作來源於「 973 -無人作戰飛機系統」項目,以某型無人機試飛過程中拍攝的著陸場景圖像為基本研究材料,綜合利用了圖像處理技術、計算機視覺技術、射影幾何學等方法研究了跑道識別與跟蹤、進場著陸段的圖像處理、無人機著陸段飛行參數提取等相關問題。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。This paper studies the helicopter, the propeller - driven aircraft and the turbofan jet airplane echo modulating feature parameter model and analyses the echo signal feature. it gains the target echo ’ s the cyclical modulation feature by using the complex ar frequency range bispectrum slice. because traditional method in extraction airborne radar ’ s radiant signal feature time has certain insufficiency, this paper proposes the approximate entropy and the norm entropy as the passive feature parameter in the airplane
由於傳統方法等在提取機載雷達輻射源信號特徵的時候存在著一定的不足,本文提出把近似熵和范數熵作為飛機目標識別的無源特徵參數,給出了提取相應特徵熵的演算法,實現對機載雷達輻射源信號的識別,通過和機載雷達類型的匹配,實現對目標的識別。
