INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING METHOD

To enable the measurement of a ground position of an aerial sign by a simpler method.SOLUTION: An information processing system includes a plurality of aerial signs provided with a GNSS reception part, a first position measurement part for measuring a ground position of an aerial sign on the basis of a plurality of signals received by the plurality of aerial signs, and a processing part for adding position information of a UAV during photographing to a picked-up image caught by the UAV, estimating a ground position of an aerial sign included in the picked-up image by using the added position information, detecting the aerial sign from the picked-up image including the aerial sign caught by the UAV on the basis of the estimation, and associating the position of the detected aerial sign in the picked-up image with the ground position. The aerial sign has a shape in which a plurality of polygons are combined to be arranged or a shape in which a plurality of circles having a different radius are arranged concentrically, and hues corresponding to colors of areas adjacent to each other have a different prescribed threshold or more, or one of them is black. The GNSS reception part is arranged at the position of almost the center of the aerial sign.SELECTED DRAWING: Figure 4 【課題】より簡単な方法で対空標識の地上位置を測定することを可能にする。【解決手段】ＧＮＳＳ受信部を備えた複数の対空標識と、複数の対空標識により受信された複数の前記信号に基づいて対空標識の地上位置を測定する第１の位置測定部と、ＵＡＶにより撮像された撮像画像に撮影時のＵＡＶの位置情報を付加し、付加された位置情報を用いて撮像画像に含まれる対空標識の地上位置を推定し、前記推定に基づいて、ＵＡＶにより撮像された対空標識を含む撮像画像から対空標識を検出し、検出された撮像画像中の対空標識の位置と前記地上位置とを対応付ける処理部と、を備える。対空標識は、複数の多角形を組み合わせて配置した形状、又は異なる半径を有する複数の円が同心円状に配置された形状であり、互いに隣接した領域の色彩に対応する色相は所定の閾値以上異なるか、一方が黒色であり、ＧＮＳＳ受信部は、対空標識の略中央の位置に配置される。【選択図】図４
