Patent abstract
An external controller specifies the direction of a surveying instrument with respect to a laser marking instrument to calculate a first relative angle as an angle relative to the surveying instrument, calculates a second relative angle as an angle relative to a target line based on design information, and calculates a differential angle between the first relative angle and the second relative angle, thereby rotating a marking laser emitter by the differential angle to project marking laser light onto the target line.
