• 中文摘要： 本文提出利用單眼半圓式跑道影像決定飛行物體位置的新方法。標準的跑道通常由兩條平行直線及兩個半圓所組成。從單眼的半圓式跑道影像，利用影像處理及數值分析技巧可以粹取出跑道的邊界。安置在飛行物體上之相機的位置和方向，不需要點點對應，由地面上和影像上的半圓式跑道係數可以計算出。此方法的優點是此解為唯一的，解析的，且不需要疊代計算。由實驗結果的高精度顯示本文所提之方法具有可行性。誤差分析也包含在內，可用以決定定位之精度。
• 英文摘要： A new method is proposed for determining the location of a flying object using a single view of asemi-circle running track. A standard running track usually is composed of two parallel line segments andtwo semi-circles which are connected to the ends of the two line segments. From a monocular image of asemi-circle running track, image processing and numerical analysis techniques are employed to extract theboundary of the running track. The position and the orientation parameters of the camera mounted on theflying object can then be computed using the coefficients of the running track without solving the pointcorrespondence problem between the global space and the image. A major merit of the method is that thesolution can be uniquely and analytically determined without iterative computation. Experimental resultswith high location accuracy show the feasibility of the proposed approach. Error analysis useful for deter-mining location accuracy is also included.
