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.

Abstract: A survey system including a movable photographing device, a surveying device, and an analysis device. The movable photographing device includes a camera mounted on a UAV and taking a plurality of images P for photogrammetry, and a GPS unit including a first time stamping portion stamping a first time Tc relating to a photographing time on the image P taken. The surveying device determines a position of the movable photographing device, and includes a second time stamping portion stamping a second time Tt relating to a surveying time on a survey result R determined above. The analysis device includes a photographing position analysis portion associating each survey result R with a photographing position of the respective image P based on the first time Tc and the second time Tt, and generating data for photogrammetry.
