Mobile Augmented Reality in support of building damage and safety assessment

Abstract

Abstract. Rapid and accurate assessment of the state of buildings in the aftermath of a disaster event is critical for an effective and timely response. For rapid damage assessment of buildings, the utility of remote sensing (RS) technology has been widely researched, with focus on a range of platforms and sensors. However, RS-based approach still have limitations to assess structural integrity and the specific damage status of individual buildings. Consequently, ground-based assessment conducted by structural engineers and first responders is still required. This paper demonstrates the concept of mobile Augmented Reality (mAR) to improve performance of building damage and safety assessment in situ. Mobile AR provides a means to superimpose various types of reference or pre-disaster information (virtual data) on actual post-disaster building data (real building). To adopt mobile AR, this study defines a conceptual framework based on Level of Complexity (LOC). The framework consists of four LOCs, and for each of these the data types, required processing steps, AR implementation, and use for damage assessment, are described. Based on this conceptualization we demonstrate prototypes of mAR for both indoor and outdoor purposes. Finally, we conduct a user evaluation of the prototypes to validate the mAR approach for building damage and safety assessment.

A process-driven and need-oriented framework for review of technological contributions to disaster management

“…Multivariate texture features were reported helpful in the efficient classification of debris from non-debris regions for post-disaster damage assessment. In the same year, Kim et al [82] proposed the use of mobile augmented reality to facilitate the process of post-disaster structural damage assessments and safety analysis. A framework was introduced to support the adaptability of virtual reality technology and a prototype system was developed to demonstrate its effectiveness.…”

Flexible development of location-based mobile augmented reality applications with AREA

“…These works also show that engineering aspects are crucial for the development of mobile augmented reality applications. Kim et al (2016), in turn, discusses various types of location-based augmented reality scenarios. More precisely, issues that have to be particularly considered for a specific scenario are discussed in more detail.…”

Research on the safety assessment of RC workshop buildings in earthquake site based on the fuzzy comprehensive evaluation

“…The seismic performance of buildings will be changed greatly after earthquake 3–5 . After earthquake, rapid and accurate building damage and safety assessment is critical 6–8 . The safety assessment of buildings in earthquake site refers to the safety assessment of damaged buildings under an expected earthquake by checking the seismic damage and the seismic capacity of the original building in the emergency period after a strong earthquake 9 .…”
