Measure with reference to the horizontal direction toward. The rotation angle of the range finder 7 can be automatically measured, for example, via an encoder or the like. If the range finder 7 measures the distance P−S 2 when the range finder 7 is rotated by an angle θ 2 from the reference direction,
