Application to Heat Stroke Prevention Technology Based on Visualization of Hemodynamic Changes Using a General Single-Lens Camera

Abstract

In these days, the number of patients suffering from heat stroke is increasing. But, to determine heat stroke, most people tend to be empirical evidence. Therefore, we recognized the need for technology to prevent heat stroke before it happens. We have converted a single-lens camera into a near-infrared camera to measure the hemodynamic changes before and after exercise. In this study, we measured the IR images from human skin surface and calculated the reflectance images from IR images. And we performed three types of experiments, 1) Forearm measurement in the darkroom, 2) Sole measurement in the darkroom, 3) Outdoor forearm measurement. The results show that the relationship between reflectance images and hemodynamic changes, it was suggested that it could be used as a guide to prevent heat stroke.
