Abstract: A mobile body is controlled even in a place in which a navigation signal is difficult to receive from a navigation satellite. A three-dimensional information processing unit operates a device or a functional part which measures three-dimensional coordinates of a controlled target and operates a laser scanner or a laser scanning part which obtains three-dimensional point cloud data of the target. The unit includes a positioning section that operates the device or the functional part which measures the three-dimensional coordinates, to calculate the three-dimensional coordinates, and includes a scan controlling section that obtains the three-dimensional point cloud data from the laser scanner or the laser scanning part. The unit also includes a range calculator that calculates a movable range of the target from the three-dimensional coordinates and the three-dimensional point cloud data, and includes a controlled target position calculator that calculates a position of the target in the movable range.

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.
