Collaborative Visualization of Environmental Simulation Result and Sensing Data Using Augmented Reality

Abstract

Thermal environment deterioration is a serious problem. To solve this problem, qualitative and quantitative evaluation is necessary. Computational Fluid Dynamics (CFD) analysis result and sensing data should be represented more comprehensively so that novice people can understand and join discussion on environmental design. In this research, therefore, a visualization technique is proposed, combining visualization of CFD analysis result or sensing data with Augmented Reality (AR), which can superimpose virtual objects onto the video image. By using this system, multiple users, wearing head mounted displays (HMD) can view the analysis result or sensing data onto the video image of outdoors and can investigate countermeasures to solve environmental problems cooperatively. So far, an AR-based outdoor CFD analysis result visualization system has been developed by adopting our accurate registration technique for outdoor AR using point cloud data. An AR-based outdoor sensing data visualization system is under development.
