Component based engineering of a mobile BIM-based augmented reality system
2014
Abstract Over the last decade, building information models (BIM) have become increasingly popular. Yet their use on construction sites where the digital materializes, is limited. A technology that can bridge the gap between the digital and the real world is augmented reality (AR). We analyze this gap and the AR potential and present how the component based software engineering method can be used to efficiently implement a BIM-based AR system for construction. An architecture of the software system is proposed and verified by a prototype which was tested in a real construction project. We found out that the use of AR can significantly narrow the semantic gap between the digital model and the real world; that components for creating a BIM-based AR systems exist but currently do not scale well to large models; and that the use in AR applications creates additional requirements the for BIM models and tools, particularly related to the BIM's 4th dimension.
