3D Thermal Imaging: Fusion of Thermography and Depth Cameras

This work presents an approach to automatically create 3D thermal models using multi-perspective measurements with a multimodal camera system consisting of a thermal camera and a depth camera. Additional attributes such as color can also be added to the model. The paper centers its attention on the geometrical calibration of the cameras and the validation of the results. The design of an adequate calibration target is discussed and different options are evaluated. To expose the applicability of the approach two inspection tasks are used as examples.
