DEVELOPMENT OF AN AR VISUALIZATION SYSTEM USING ARKIT FOR UNDERGROUND STRUCTURE AND EXAMINATION OF HIGH ACCURACY OF SUPERPOSITION IN ALIGNMENT

Abstract

 This paper presents the development of AR visualization systems for underground structure using ARKit. We developed two AR systems: a system to superimpose the CAD model of the underground buried structure on the design drawing and a system to superimpose the CAD model on site. In the system that superimposes the CAD model on the design drawing, we tried to superimpose the city model at the same time in order to easily grasp the positional relationship. In addition, in the system for superimposing CAD models in the field, we examined the masking processing method and the method for improving the accuracy of the superimposition position of the CAD model. In order to verify the effectiveness of this system, The present systems are applied to an actual example of underground structure.
