Combination of Image-Based Documentation and Augmented Reality for Structural Health Monitoring and Building Pathology

Abstract

With the current deterioration rate of existing infrastructure, the importance of intervention and preservation efforts such as on-site visual inspections, non-destructive evaluation, structural health monitoring (SHM), and building pathology are on the rise. A critical aspect of these intervention and preservation methods is the visualization and accessibility of large, heterogeneous data sets. To enable diverse stakeholders to make informed choices, data and metadata for the built environment needs to be directly integrated into a user's viewing environment. To address this challenge, a human-machine interface which organizes these types of data and provides actionable information is necessary. The main aim of this work is to develop a preliminary framework for documenting and visualizing data about the built environment both on and off site using a combination of image-based documentation and augmented reality (AR). While this work illustrates preliminary annotation mechanisms such as drawing, the concept of projecting data between the image-based environment and the AR environment is the main contribution of this work. This method was applied to test objects as well as case studies in SHM and building pathology.

Estado de la investigación sobre la patología de la construcción: un análisis bibliométrico

“…El enfoque de estas nueve fuentes hace referencia en su mayoría al análisis patológico mediante el uso de técnicas no invasivas, principalmente en los diferentes materiales de construcción para edificaciones tanto consideradas patrimonio como aquellas sin declaratoria. Como se observa en la figura 2 el aumento de publicaciones a partir del año 2009 y los congresos con indexación en Scopus más recientes como Rehabend desde el 2014, se han presentado conforme se ha ido desarrollando y aplicando estas técnicas no invasivas en edificaciones [23], [24], [25].…”

A Review of Augmented Reality Applications in Civil Infrastructure During the 4th Industrial Revolution

“…Dang et al (2018) developed 3D digital twin models with related damage records for typical bridge structures as a database to predict a similar structure's reliable future performance. Napolitano et al (2019) developed a novel AR framework for data visualization during the structural inspection.…”

Close-Range Sensing and Data Fusion for Built Heritage Inspection and Monitoring—A Review

“…These technological solutions include equipment for metric data acquisition, such as total stations, laser scanners, Global Navigation Satellite System (GNSS) receivers, imaging sensors, software for processing, managing, visualizing, and disseminating the recorded data and their derivative products, and computer hardware for running the software [18,19]. The technical developments in photogrammetry-based and scanning-based reality capturing have allowed for easy-to-use instrumentation, automatized three-dimensional (3D) shape reconstruction, and color texturing methodologies for documenting the conditions of historic structures, which enables monitoring and on-site inspections [20,21]. An equally important advantage of these advancements is that, through the generation of high-fidelity 3D models and point clouds, they have allowed for virtual fruition-remote inspection, maintenance management, and valorization via mobile and web-based platforms that utilize smart algorithms, augmented reality, and spatially aware content [22][23][24][25][26][27][28][29].…”
