DEVELOPMENT OF THE BRIDGE INSPECTION EDUCATION SYSTEM USING MR HEAD MOUNTED DISPLAY

Abstract

 Ministry of Land, Infrastructure, Transport and Tourism had amended the Road Law Enforcement Order at 2014, in order to find early damaged conditions and visual inspection is required every 5 years by the road administrators. Therefore, the amount of inspection work increases. Hence, it is need expert inspector for bridge maintenance who have specialized knowledge. With this background, many workshops are held in everywhere as a bridge inspector to maintain bridges. However, normally workshop is carried out on-site. That is to say, if weather condition is rainy, workshop is canceled. And another condition such as traffic and safety are problem to be held in workshop.

 Therefore, we focused on MR technology that can realize an immersive experience in virtual space. In this study, we were developing a bridge inspection experience system with an MR Head-Mounted-Display that can simulate inspection work in a VR space for the education. The target of the bridge material is the inspection of the reinforced concrete bridges. 3D-VR models is made from real bridge photos. Thus, a young inspector can be experienced proximity visual inspection. In addition, in the impact inspection experience, the young inspector shakes the motion-controller instead as a checked hammer and hits the bridge, and marks damaged area using the hitting sound.

 In this paper, we describe how to developed this system and how to utilize, and through the developed system as a result it show the efficiently to use MR technique for bridge inspector.
