PROBLEM TO BE SOLVED: To provide a survey system which can precisely specify the position of imaging and can increase the accuracy of photographic surveying by precisely relating the time of taking an image by a mobile imaging device and the time of survey made by a survey device to each other.SOLUTION: A survey system 1 includes a mobile imaging device, a survey device 3, and an analysis device 4. The mobile imaging device has a camera 11 equipped in a UAV for taking a plurality of images for photographic surveying and a GPS unit 14 having a first-time provision unit 20 for providing a first time Tc relating to an imaging time to a taken image. The survey device 3 has a second-time provision unit 43 for measuring the position of the mobile imaging device and providing a second time Tt relating to a survey time to the result R of the measurement. The analysis device 4 has an imaging position analysis unit 50 for relating the position of imaging each image P to each survey result R based on the first time Tc and the second time Tt and generating data for photographic surveying.SELECTED DRAWING: Figure 2

    【課題】移動撮影装置で撮影した画像の撮影時期と、測量装置により測量した測量時期とを正確に対応付けることで、撮影位置を精密に特定し、写真測量の精度を向上させることのできる測量システムを提供する。【解決手段】測量システム1は、移動撮影装置と測量装置3と解析装置4とを備え、移動撮影装置は、UAVに搭載され写真測量用の画像を複数撮影するカメラ11と、撮影した画像に撮影時期に関する第1の時刻Tcを付与する第1の時刻付与部20を有するGPSユニット14と、を有し、測量装置3は移動撮影装置の位置を測量し、その測量した測量結果Rに、測量時期に関する第2の時刻Ttを付与する第2の時刻付与部43と、を有し、解析装置4は、第1の時刻Tcと第2の時刻Ttとに基づき各測量結果Rを各画像Pの撮影位置に対応付けて、写真測量用のデータを生成する撮影位置解析部50を有する。【選択図】図2
