Condition assessment of special auxiliary structures in sewer systems supported by building information modeling (BIM) and augmented reality (AR)
Abstract
In the first phase of the research project, selected SBW are to be recorded by means of photogrammetry. Afterwards, these images will be supplemented by 3D/BIM models of the SBW. In the last step, the two components will be enhanced by augmented reality (AR). The following goals are to be be achieved within the scope of this project: * With the help of photogrammetric images of SBW, they can be represented in 3D. depicted. Structural and safety-related damage can therefore be made visible to be made visible on the PC in a clear and easily understandable way. * Within the scope of the photogrammetric recording, measurements of the SBW are necessary. These can be used for subsequent hydraulic calculations, e.g. according to ÖWAV RB 19 (2007). * In addition, the condition catalog created in the ÖWAV-KAN preliminary project is to be catalog will be extended by a 3D-condition description. * When intersecting the photogrammetry model with the 3D-/BIM-model existing building plans can be checked for correctness and completeness. completeness. In addition, by linking the two models the precise delineation of structural damage and the determination of masses for the subsequent rehabilitation will be facilitated. * A further project goal is the simpler determination of causes with regard to structural damage to the SBW (e.g. foreign pipeline carriers, foreign construction sites, influence of nature, etc.). * With the fusion of photogrammetric images and 3D-models with AR, changes in the condition of the SBW can be recorded by the periodic inspection by operations personnel can be captured. * This new approach should furthermore serve as an essential support for future future construction measures at and near the SBW.
