Abstract: A survey data processing device includes a panoramic image data receiving unit, a point cloud data receiving unit, a similar part designation receiving unit, and a correspondence relationship determining unit. The panoramic image data receiving unit receives first and second panoramic images that are respectively obtained at a first point of view and a second point of view. The point cloud data receiving unit receives first point cloud data that is obtained by a first laser scanner and receives second point cloud data that is obtained by a second laser scanner. The similar part designation receiving unit receives designation of a part that is the same or similar between the first and second panoramic images. The correspondence relationship determining unit determines a correspondence relationship between the first and second point cloud data on the basis of the first and second point cloud data corresponding to the same or similar part.

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: A pile head analysis system captures a plurality of images of a construction site including a pile using a camera mounted on an unmanned aerial vehicle (UAV), acquires the images, generates a three-dimensional model of the construction site, detects a pile head from the three-dimensional model, and determines consistency between the detected pile head and preliminarily acquired design information.

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.
