| Outline of Final Research Achievements |
Recently, inundations in underground structures have been increasing due to frequent localized heavy rainfalls in Japanese urban areas. To provide the information on the predicted inundation risks, location-based services are preferable for individual users. However, GPS does not function in underground spaces. This study proposes an augmented reality (AR) visualization of underground flood situations based on a visual location technique. The proposed method acquires the 3D coordinates of the natural features from prerecorded images. The user’s viewpoint can be estimated by corresponding 3D coordinates and natural features of the user photographed image, solving a Perspective-n-Point (PnP) problem. Then the water surfaces expressed by CG is superimposed on the photograph from the viewpoint of the user. We experimented with an actual railway station located in the underground. The reproducibility of the user’s viewpoints was verified, and view-dependent AR representation was achieved.
