Abstract: Disclosed is a measurement device including: a distance measurement unit that has a light-generating element, a measurement light emission unit, a light reception unit, and a light reception element and measures a distance to a measurement target on the basis of a light reception signal; a deflection unit that is capable of performing scanning with measurement light; and a control unit that controls the distance measurement unit and the deflection unit. The control unit finds a surface of the measurement target, generates a grid having lines that are arranged at regular intervals on the surface of the measurement target and include a component parallel to a reference direction and a component perpendicular to the reference direction, and controls a deflection behavior of the deflection unit so that a scanning track of the measurement light traces the lines of the grid.

Abstract: A technique is provided for measuring attitude of an aerial vehicle without using a highly accurate IMU. A total station (TS) for tracking a UAV includes a laser scanner. The laser scanner is made to emit laser scanning light to the UAV that is flying. The UAV has four identifiable targets, and identification and locating of the four targets are performed by means of laser scanning. The attitude of the UAV is calculated on the basis of the locations of the four targets.
