Abstract

In the field of dynamic engineering and biomechanics, the digital video recorder (DVR) is widely applied to visualize two- and three-dimensional images of moving machineries and human beings using several visual markers on the body surface. On the other hand, high-speed infrared radiometers (IR) are often used to visualize and analyze the dynamic image of moving body as well as their temperature distributions. IR radiometric systems are mainly applied to detect external and internal flaws of dynamic components and etiological causes of human beings in the field of industry and medicine, as remote-sensing non-destructive and diagnostic methods. Simultaneous visual studies of dynamic motion and temperature distribution of the moving body are very little to apply industrial and biological engineering systems. Quantitative analysis using the high-speed IR system was carried out to visualize and motion and thermal images of the moving bodies simultaneously. In this study, the high-speed IR system measures the dynamic and thermal images of the moving bodies using passive and artificial thermal markers and friction marks of the moving interface boundary. Dynamic motion characteristics of measured images by digital video recorder DVR and IR were quantitatively compared. Characteristics of single- and multi-flash imaging methods were measured and analyzed using the triggered motion coder. The IR radiometric systems are quite useful in the visualization and analysis of the motion and thermal distribution of the moving mechanical components, human bodies and their supporting components. These characteristics are well related to motion physiology, human welfare, health management etc.
