An automatic generation method of augmented-reality (AR) Contents by image annotating for supporting inspection of power-distribution facilities is proposed. By means of the proposed method, a worker records inspection results by taking picture of a target and annotating defect icons to the corresponding part of the picture. Location of each annotated icon on the picture is automatically linked to the location of real facilities and saved in database. When the worker inspects the target through a camera mounted on a tablet, alerts about defects found in previous inspections are automatically displayed by AR based on previous annotated pictures. As a result, the system can improve efficiency and reliability of inspection works because the workers can inspect target while referring to check points which should be inspected with extreme caution. In future work, practicability of the proposed method will be evaluated through prototyping.
