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.

Abstract: Provided is a work management system enabling real-time inspection by simultaneously performing work and measurements. The work management system includes a tool including a communication unit and a trigger switch, a camera unit including a communication unit, a camera capable of identifying 3D camera coordinates from an image, a posture detecting device configured to acquire camera posture information, a control unit, and a prism, and a surveying instrument including a communication unit, a tracking unit, a distance-measuring unit, an angle-measuring unit, and a control unit, wherein upon detection that the trigger switch has been used, the camera unit collects camera posture information by the posture detecting device, a tool image by the camera, position coordinates of the prism measured by the surveying instrument, and orientation information of the camera unit viewed from the surveying instrument, and obtains and stores position coordinates of a tip end position of the tool.
