Robust thermal camera calibration and 3d mapping of object surface temperatures

In this paper we consider the issues involved in the 3D mapping of object surface temperatures from a system of thermal and normal stereo cameras. Of particular focus are issues related to integrated thermal and stereo camera calibration using a common visible and thermal calibration grid and the development of robust 3D thermal mapping algorithms that allow for seamless surface temperature calculations. Finally we have examined the class of objects that this system can robustly apply to as well as pinpoint deficiencies in such approaches to 3D surface temperature calculations from thermal cameras.
