Distributed augmented reality for visualising collaborative construction tasks

Abstract

In this paper, a new methodology called Distributed Augmented Reality for Visualising Collaborative Construction Tasks (DARCC) is proposed. Using this methodology, virtual models of construction equipment can be operated and viewed by several operators to interactively simulate construction activities on the construction site in augmented reality mode. The chapter investigates the design issues of DARCC including tracking and registration, object modelling, engineering constraints, and interaction and communication methods. The DARCC methodology is implemented in a prototype system and tested through a case study of a bridge deck rehabilitation project. © 2009 Springer Netherlands.
