The dissipation of thermal radiation can be observed using thermal infrared cameras, which generate images based on the amount of input radiation belonging to a small part of the electromagnetic spectrum (with wavelengths from 7μm to 15μm). Since thermal imaging is a simple, contactless, non- invasive and inexpensive imaging method, it is widely applicable in industry, medicine and research. The most common type of thermal imaging involves taking and analyzing only a single thermal image, and is thus called static thermal imaging. In cases when a thermal process cannot be approximated as static, dynamic thermal imaging and analysis is applied. The idea of combining thermal imaging with 3D scanning methods has spawned in the last few years. 3D thermal imaging can have many applications and purposes, ranging from thermogram rectification, to the creation of standardized 3D thermal models of various subjects that can later be used for comparison and evaluation. Although 3D thermal imaging systems exist, all of the examined ones were targeted on the acquisition and analysis of static 3D thermal models. This paper presents the development of a dynamic passive 3D imaging system, or in short – 4D thermography system. The workflow of the designed concept is outlined, and the components of the constructed system are thoroughly explained. The process of calibration of the system is described, as well as the methods of motion detection and analysis. A great emphasis is given on the possible medical applications of a 4D thermography system, such as medical diagnostics, human locomotive system rehabilitation and health status monitoring over longer time periods.
