Abstract: A survey data processing device includes a point cloud data receiving unit, a vertically cut section generating unit, and a vertical position adjusting unit. The point cloud data receiving unit receives first point cloud data and second point cloud data that are respectively obtained at a first instrument point and a second instrument point. The vertically cut section generating unit cuts the first point cloud data and the second point cloud data at a vertical plane containing the first instrument point and the second instrument point to obtain a vertically cut section of each of the first point cloud data and the second point cloud data. The vertical position adjusting unit matches vertical positions of the vertically cut sections of the first point cloud data and the second point cloud data as viewed from a direction perpendicular to the vertical plane.

Abstract: A technique enables intuitive understanding of a directional relationship between a photographed image and a wide area image, such as an electronic map. An image processing device includes a display controlling unit that displays a quadrangular-shaped photographic image, which is photographed from an aerial vehicle, displays a mark indicating a photographing position of the quadrangular-shaped photographic image, on a wide area image, and performs highlight display in accordance with a corresponding relationship between a direction of the quadrangular-shaped photographic image and a direction of the mark.

Abstract: An analysis system for analyzing inclination of column members includes a laser scanner, a server, and an information terminal. The server includes a data acquisition unit configured to acquire three-dimensional point cloud data of the column members generated by the laser scanner, a surface detector configured to detect surfaces of the column members based on the three-dimensional point cloud data, and an inclination analyzer configured to analyze inclination of the column members by calculating inclination of the surfaces detected by the surface detector.
