To achieve accuracy of measurement data and efficiency of work related to measurement in measurement using an unmanned aircraft.SOLUTION: In a three-dimensional information measurement system of a measurement object using an unmanned aircraft mounted with a camera, a processing device comprises: an image data acquisition unit 103 which acquires a photographed image of a measurement object while making the unmanned aircraft fly on the basis of a first flight plan; a growth data creation unit 104 which creates growth data of the measurement object on the basis of the image data; an entire map creation unit 105 which creates an entire map related to the measurement object including the growth data; a difference determination unit 108 which determines a difference between the entire map created at a time t1 and the entire map created at a time t2 subsequent to the time t1; and a flight plan creation unit 110 which creates a second flight plan for photographing a portion where a difference occurs by the unmanned aircraft. In the second flight plan, imaging is performed on a portion where a difference of the measurement object occurs in more detail in comparison to the first flight plan.SELECTED DRAWING: Figure 2 【課題】無人航空機を用いた計測において、計測データの精度と計測に係る作業の効率を両立する。【解決手段】カメラを搭載した無人航空機を用いて被計測対象の三次元情報計測システムにおいて、処理装置は、第１の飛行計画に基づき無人航空機を飛行させつつ被計測対象の撮影画像を取得する画像データ取得部１０３と、画像データに基づき被計測対象の成長データを作成する成長データ作成部１０４と、成長データを含む被計測対象に係る全体マップを作成する全体マップ作成部１０５と、時刻ｔ１に作成した全体マップと時刻ｔ１より後の時刻ｔ２に作成した全体マップとの差を判定する差異判定部１０８と、差が生じた部分を無人航空機で撮影する第２の飛行計画を作成する飛行計画作成部１１０とを備える。第２の飛行計画は、第１の飛行計画に比べ、より詳細に被計測対象の差が生じた部分の撮影を行う。【選択図】図２
