Abstract: A surveying apparatus has a combined structure of a total station and a laser scanner. The surveying apparatus includes a point cloud data acquiring unit, an abnormal part detecting unit, an abnormal part position acquiring unit, and an automatic sighting controller. The point cloud data acquiring unit acquires first point cloud data and second point cloud data obtained by laser scanning that is performed on an object to be inspected at a time interval. The abnormal part detecting unit calculates a difference between the first and second point cloud data to detect a part of the object to be inspected, at which position information varies, as a detailed-inspection target part. The abnormal part position acquiring unit acquires a position of the detailed-inspection target part. The automatic sighting controller controls to make the total station sight the detailed-inspection target part, based on the position of the detailed-inspection target part.

Abstract: Efficiency of a technique for performing laser scanning and photography simultaneously is improved. A laser scanning apparatus includes a horizontally rotatable horizontal rotation unit, a rotation controller, and a processor or circuitry. The horizontal rotation unit includes cameras and a vertical rotation unit that performs laser scanning in an upper-lower direction. The rotation controller controls rotation of the horizontal rotation unit. The processor or circuitry performs a process of not selecting some pieces of laser scanning data that is obtained by laser scanning in the upper-lower direction. Laser scanning and photography that uses the cameras are performed while the horizontal rotation unit is horizontally rotated. The rotation of the horizontal rotation unit is decelerated in performing photography. The processor or circuitry does not select some pieces of laser scanning data that are obtained by laser scanning in the upper-lower direction during the deceleration.

Abstract: Laser scanning is performed along a transverse section of a tunnel while the amount of scanning is reduced as much as possible. A laser scanning apparatus includes a horizontal rotation unit, a vertical rotation unit disposed on the horizontal rotation unit, and an optical unit disposed on the vertical rotation unit and configured to emit and receive laser scanning light. A method includes obtaining laser scanning data of right and left wall surfaces of a tunnel, calculating a straight line that connects the right and left wall surfaces and that crosses a perpendicular line passing a position at which the laser scanning apparatus is set up, and calculating a direction orthogonal to the straight line in a horizontal plane, and performing laser scanning of a transverse section of the tunnel while the vertical rotation unit is rotated around a rotation axis in the calculated direction.

Abstract: A technique for enabling efficient surveying operation that uses a light-reflecting target is provided. A surveying apparatus is configured to survey a reflecting prism and includes a controller, a surface calculator, and a position calculator. The controller performs positioning on three or more points on the set-up surface on which the reflecting prism is set up, by using laser light. The surface calculator calculates a plane of the set-up surface based on the positioning data of the three or more points in a case in which the position of the reflecting prism is surrounded by the three or more points in terms of a horizontal plane. The position calculator calculates a point of intersection of the plane and a straight line from the position of the reflecting prism to the plane, as a position on the set-up surface, at which the reflecting prism is set up.
