Real-Time Thermal Imaging Using Augmented Reality and Accelerated 3D Models

We present an innovative method to allow real-time visualisation of temperature fields on power electronic circuits using augmented reality. A real-time time-domain simulation incorporating the Block Arnoldi model order reduction techniques is implemented in the Unity game engine. Traditional methods run too slowly whereas the developed system allows an example model with 9232 thermal nodes to be dynamically simulated in real-time at a speed fast enough to allow for a smooth augmented reality visualisation. The aim is to show the feasibility of the technology and that it could be applied to visualising electromagnetic fields in future work.
