PROBLEM TO BE SOLVED: To simplify a field angle adjustment procedure in a monitoring system.SOLUTION: A field angle adjustment method being the field angle adjustment method of a monitoring system 1 comprising a camera 2A that images a first area Rand a camera 2B that images a second area Rbeing more remote than the first area R, comprises the steps of: setting a target of a common area Rincluded in both areas Rand R; calculating arrangement of a mark Cindicating a display objective of the target on an image Jby the camera 2A; displaying the mark Con the image J; adjusting a field angle of the camera 2A such that the target is adapted to the mark Con the image J; calculating arrangement of a mark Cindicating the display objective of the target on an image Jby the camera 2B; displaying the mark Cat a position calculated on the image J; and adjusting a field angle of the camera 2B such that the target is adapted to the mark Con the image J.SELECTED DRAWING: Figure 4

    【課題】監視システムにおける画角調整の手順の簡素化を図る。【解決手段】画角調整方法は、第1領域R2Aを撮影するカメラ2Aと、第1領域R2Aよりも遠い第2領域R2Bを撮影するカメラ2Bと、を備えた監視システム1の画角調整方法であって、領域R2A、R2Bの両方に含まれる共通領域R2Cにターゲットを設定する工程と、カメラ2Aによる画像J1上でのターゲットの表示目標を示すマークC1の配置を計算する工程と、マークC1を画像J1上に表示する工程と、画像J1上でターゲットをマークC1に合わせるようにカメラ2Aの画角を調整する工程と、カメラ2Bによる画像J2上でのターゲットの表示目標を示すマークC2の配置を計算する工程と、マークC2を画像J2上の計算された位置に表示する工程と、画像J2上でターゲットをマークC2に合わせるようにカメラ2Bの画角を調整する工程と、を含む。【選択図】図4
