Claim 17:
18. A work management method comprising:
a step of causing a surveying instrument to start automatic tracking by a tracking unit;
a step of causing a camera unit to start measurements by a camera and a posture detecting device;
a step of acquiring trigger information of a tool;
a step of calculating position coordinates of a tip end position of the tool; and
a step of storing the position coordinates of the tip end position of the tool, wherein
the tool includes a communication unit and a trigger switch;
the camera unit includes the camera and the posture detecting device, a communication unit, a control unit configured to control the camera and the posture detecting device, and a prism, the posture detecting device being configured to acquire camera posture information of the camera, the camera being capable of identifying 3D camera coordinates from an image; and
the surveying instrument includes a communication unit and the tracking unit which is configured to automatically track the prism by tracking light, a distance-measuring unit configured to measure a distance to the prism by distance-measuring light, an angle-measuring unit configured to measure an angle to the prism, and a control unit configured to control the tracking unit, the distance-measuring unit, and the angle-measuring unit,
wherein upon detection that the trigger switch has been used by communication from the tool, 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 the tip end position of the tool.
