PROBLEM TO BE SOLVED: To obtain an airport surface monitoring device capable of contributing to an improvement in tracking accuracy when tracking a target object.SOLUTION: A three-dimensional position calculation unit 4 estimates a position of a target object on an airport surface in the three-dimensional coordinates using estimation results of grounding position coordinates and altitude information of the airport surface in the three-dimensional coordinates. A measurement error estimating unit 5 calculates a measurement error of the target object at the position in the three-dimensional coordinates using image coordinates of the target object and resolution data 100 indicating the resolution of the three-dimensional coordinates with respect to the image coordinates. A result output unit 6 outputs the image coordinates of the target object, the position of the target object in the three-dimensional coordinates, and the measurement error.SELECTED DRAWING: Figure 1

    【課題】目標物体の追尾を行う際の追尾精度の向上に寄与することのできる空港面監視装置を得る。【解決手段】3次元位置計算部4は、接地位置座標の推定結果と3次元座標における空港面の高度情報とを用いて、空港面上の目標物体の3次元座標における位置を推定する。計測誤差推定部5は、目標物体の画像座標と、画像座標に対する3次元座標の分解能を示す分解能データ100とを用いて、目標物体の3次元座標の位置における計測誤差を計算する。結果出力部6は、目標物体の画像座標と、目標物体の3次元座標の位置と、計測誤差とを出力する。【選択図】図1
