Cooperative Reinforcing Bar Arrangement and Checking by Using Augmented Reality

Abstract

In this research, a bridge product model named New IFC-BRIDGE was developed to represent entities of various types of bridges in a standardized manner. To solve problems identified in planning and design of reinforcing bar works, a cooperative reinforcing bar arrangement support system using Augmented Reality technology was developed. In this system, multiple users can move tangible markers that represent entities of reinforcing bars and that are linked to computer graphics images represented from the New IFC-BRIDGE product model data. A prototype system was developed by deploying head mounted displays with video cameras. Furthermore, to enhance the reinforcing bar checking task at construction sites, a cooperative reinforcing bar checking support system was developed by using AR technology. The test of the prototype system showed the practicality of the system, and some problems were identified for future study.
