Application of building information modelling, extended tracking technique and augmented reality in building operating management

Abstract

This paper presents a combination of Augmented Reality (AR), Extended Tracking Technique (ETT) and Building Information Modelling (BIM) to interact with building information in real-time on construction site. Using this method, we have programmed an application running in mobile device to help manage and operate the building facility systems. In this application, the building model and its information are stacked and augmented on the mobile device camera when projecting on the target image mounted on the building. ETT allows extending the object displayed on the screen, even when the mobile device camera no longer captures the target image. Based on this process, engineers can interact with the software to add, change the information needed of facilities on construction site, such as size, manufacturer, date of maintenance, date of replacement, device life cycle, etc.
