  1. In the application of mini - micro - robot visual perception, there is a need for fish - eye lenses for capturing wide field of view for navigation. though fish - eye lenses provide a wide field of view ( 180 ), they introduce significant distortion in images and the acquired images are quite warped, which makes conventional camera calibration algorithms no longer work well. this paper presents an accurate calibration framework for fish - eye lens ( a high distortion lens ) camera stereo vision system. the accurate calibration model is formulated with radial distortion, decentering distortion and thin prism distortion based on the fisheye deformation model. using fish - eye and non - linear camera model, the author employs levenberg - marquardt method to realize precise non - linear calibration for wide - view - scene dense depth image recovery

    魚眼鏡頭成像立體視覺系統在微小型機器人視覺導航和近距離大視場物體識別與定位中有著廣泛的應用.盡管魚眼鏡頭攝像機具有很大的視場角（接近180 ） ，但同時也引入嚴重的圖像變形，常規的攝像機標定方法無法使用.該文提出一種標定魚眼鏡頭攝像機立體視覺系統的方法.在魚眼鏡頭變形模型的基礎上，通過考慮魚眼鏡頭成像的徑向變形、偏心變形和薄棱鏡變形，建立了魚眼鏡頭成像的精確成像模型，然後，利用非線性迭代演算法，精確求解攝像機外部參數、內部參數.實驗表明，使用該方法得到的立體視覺系統參數滿足精確恢復大場景稠密深度圖的要求
  2. Since the controller concerned did not positively apply vertical separation between the two aircraft or take prompt recovery action when they came close to each other, a loss of standard separation occurred

    由於控制員未有為兩架航機提供適當的高度間隔，或在兩機接近時立即採取糾正行動，因而導致這次標準距離出現偏差事件。
  3. Abstract : cruise missiles have the characteristics of concealment and unexpectedness, so effectively detecting cruise missiles is the crux of cruise missiles defence. in order to increase detecting distance and discovery probability for cruise missiles, we ought to synthetically utilize various measures to make up the all directions target detecting and information communicating system with emphasis, which combines air with ground, far with near, advanced measures with traditional measures

    文摘:巡航導彈具有隱蔽和突然的特點，對巡航導彈進行有效的探測，是抗擊巡航導彈的關鍵，綜合利用各種手段，組成空中與地面相結合、遠方和近方相結合，先進手段與傳統手段相結合的全方位、有重點的目標探測與報知體系，可增大對巡航導彈的探測距離，提高發現概率。
  4.
