要約(英語): A method to identify utility poles without being influenced by the measurement errors of Global Positioning System (GPS) is proposed for an Augmented Reality (AR) system for supporting visual inspection of power distribution facilities. When a system user views a pole through a camera mounted on a tablet, the pole is identified by the proposed method, and related information is overlaid on a live camera view. The proposed method narrows down potential target poles from plural candidates by checking positional relationship of the user's location and heading, the location (latitude, longitude) of each pole, and geographical information about buildings and roads. The user's location is estimated using not only GPS but also distance between the user and pole being inspected calculated by triangulation using the tablet's height and elevation angle. The proposed method is evaluated using a prototype at a residential area and an office area. The average of GPS measurement errors is 11.8m. The result of 90 times trials shows that the proposed method uniquely identifies the target pole at a success rate of 89.3%.
