Most studies focus on surface defect detection methods with limited research addressing post-data collection and analysis processes. Typically, the inspector would need to return to the site, survey the bridge, and map the defect areas manually. The process is costly and inefficient, relying on inspector expertise. Therefore, to address these challenges, this study explores using augmented reality (AR) to improve defect mapping through enhanced visualization, geolocation, and access to previous inspection and maintenance reports. Existing research on AR in this context is minimal, prompting the need for this investigation. The proposed AR-based technique requires minimal hardware and software additions beyond what is typically available during inspection operations, making it easily replicable. Target defect will be delamination, and the mode of detection used are Infrared Thermography (IRT) and Impact Echo (IE). However, the method can be applied to any desired defect and detection method with 2D maps as the output. The technique was assessed on a mockup slab with mimic delamination and an in-service bridge. The results highlight that the proposed AR application has the potential to improve efficiency, accuracy, and collaboration during inspection and maintenance operations.Keyphrases: 2d mapping, augmented reality, bridge inspection, delamination maintenance, safety, visualization In: Wesley Collins, Anthony J.
