1. A work management system comprising:
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 of the camera, a control unit configured to control the camera and the posture detecting device, and a prism; and
a surveying instrument including a communication unit, a tracking unit 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 a tip end position of the tool.
