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 unitan image processing unitand a synchronous processing unitThe input unitis 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 unitis 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 unitis configured to specify a matching relationship between the flight route of the flight data and the estimated flight route.

Survey data processing device, survey data processing method, and program therefor

The efficiency of work for identifying reference points included in photographed images is improved. A survey data processing device includes a data receiving unitthat receives data of two still images, an operation information receiving unitthat 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 unitthat calculates exterior orientation parameters of a camera, a coordinate integrating unitfor obtaining an integrated coordinate system for describing both the locations of an unselected reference point and the camera, a back-projected image generating unitfor generating a back-projected image by back-projecting the unselected reference point in the integrated coordinate system, and a target position estimating unitthat estimates a position of the unselected reference point in a still image.

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 unitand a UI controlling unit. The storing unitstores 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 unitdisplays 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.

A target set in a to-be-measured object and used for acquiring a reference value of point-cloud data, the target includes a small circle surrounded by a frame and having the center of the target, a large circle surrounded by the frame and disposed concentrically with the small circle so as to surround the small circle, a low-luminance reflective region located between the frame and the large circle and having the lowest reflectivity, a high-luminance reflective region located between the large circle and the small circle and having the highest reflectivity, and an intermediate-luminance reflective region located inside the small circle and having an intermediate reflectivity which is higher than the reflectivity of the low-luminance reflective region and which is lower than the reflectivity of the high-luminance reflective region.
