Abstract
Pipelines play a critical role in transporting essential resources that support daily life and industrial operations. The expansion of industrial activity and infrastructure development has historically paralleled the growth of the pipeline sector. However, this growth has introduced substantial challenges, particularly in the areas of timely inspection and maintenance of critical infrastructure. To address these challenges, researchers have proposed a range of robotic and non-invasive solutions for pipeline inspection. In this study, we present a novel pre-maintenance approach that integrates mixed reality (MR) technologies using the Meta Quest Pro VR/AR headset. This method enables detailed visualization and analysis of in-pipe defects prior to physical intervention, enhancing decision-making in maintenance planning. As a result, engineers gain comprehensive insight into defect characteristics and can more accurately determine the appropriate tools and procedures required for effective maintenance.
