Abstract: The efficiency of work for identifying reference points included in photographed images is improved. A survey data processing device includes a data receiving unit 103 that receives data of two still images, an operation information receiving unit 104 that receives a selection of reference points among multiple reference points which are included in both of the two still images and have known location information, an exterior orientation parameter calculating unit 106 that calculates exterior orientation parameters of a camera, a coordinate integrating unit 110 for obtaining an integrated coordinate system for describing both the locations of an unselected reference point and the camera, a back-projected image generating unit 111 for generating a back-projected image by back-projecting the unselected reference point in the integrated coordinate system, and a target position estimating unit 112 that estimates a position of the unselected reference point in a still image.

Abstract: A technique for making multiple still images, which are photographed by a traveling mobile body, and the traveled route of the photographing correspond to each other, is obtained. A survey data processing device includes an input unit 101, an image processing unit 102, and a synchronous processing unit 103. The input unit 101 is configured to receive image data of multiple still images, which are photographed from a mobile body flying, and receive flight data, in which a flight route of the mobile body is measured. The image processing unit 102 is configured to estimate a flight route of the mobile body based on changes in positions of feature points included in the multiple still images on a screen. The synchronous processing unit 103 is configured to specify a matching relationship between the flight route of the flight data and the estimated flight route.

Abstract: An operation burden in confirming a corresponding relationship between multiple still images and a traveled route is reduced. A survey data processing device includes a storing unit 106 and a UI controlling unit 105. The storing unit 105 stores survey data, in which image data of multiple still images that are photographed from a mobile body while flying is correlated with a flight route of the mobile body. The UI controlling unit 105 displays the flight route and at least one of the multiple still images on a screen. The displayed flight route and the displayed still image are displayed on the same screen at the same time in a condition in which a corresponding relationship between the flight route and the multiple still images is determined, and a moving direction of the mobile body that photographed the displayed still image is indicated in the displayed still image.
