Title:
WORK MANAGEMENT APPARATUS AND WORK MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/099373
Kind Code:
A1
Abstract:
A camera (3) captures a starting point marker attached to a workpiece and a test marker attached to a torque wrench. A marker recognition unit (12) of the work management apparatus (10) recognizes the markers from the image data taken by the camera (3). A marker position-calculating unit (13) calculates the three-dimensional position of the test marker with respect to the three dimensional position of the starting point marker. A work correctness-assessing unit (17) assesses the work as being performed in the correct position if the three-dimensional position of the test marker calculated by the marker position-calculating unit (13) is within a screw tightening work range previously set in a work procedure storage unit (16) and notifies the worker via a reporting unit (18) that the work position is incorrect if the test marker position is not in the previously set range.
