This thesis presents a process to create 3D thermal models from multi view images captured with low cost devices, a smartphone and low cost thermal camera. 3D thermal models contribute to a data-driven assessment of chronic wounds and improve the limitations of manual measurements and subjective visual observation. Leveraging color and thermal imaging, realistic 3D thermal models are created from a limited set of images, demonstrating their effectiveness in wound assessment in a clinical study, emphasizing portability and low-cost applicability.
