PROBLEM TO BE SOLVED: To solve the problem of high risk of a UAV's collision with an obstacle around a destination because it flies in an area with many obstacles, e.g., a structure such as a building, a pole, electric wire or tree, and the problem of reduced accuracy of GNSS due to possible blocking of a radiowave from a GNSS satellite by the influence of a structure.SOLUTION: An unmanned aircraft acquires a history of a first flight to a destination. Then, the unmanned aircraft acquires a feature amount of at least one first image which was captured during the first flight. Then, the unmanned aircraft associates a feature amount corresponding to a prescribed point in the history with the history. The unmanned aircraft controls a second flight based on the feature amount and the history.SELECTED DRAWING: Figure 4
【課題】目的地の周辺では、UAVは、建物などの構造物、電柱、電線、および木などの障害物が多い地点を飛行するのでUAVが障害物に衝突してしまうリスクが高まる。構造物の影響により、GNSS衛星からの電波が遮られてしまう場合があるのでGNSSの精度が悪くなる。【解決手段】無人航空機は、目的地までの第一の飛行の履歴を取得する。第一の飛行中に撮像して得られた少なくとも1つの第一の画像の特徴量を抽出する。履歴の所定の地点に対応する特徴量を履歴に関連付ける。無人航空機は、特徴量と履歴とに基づいて第二の飛行の制御をする。【選択図】図4
