Abstract

We propose a method to observe cardiac beat from 3D shape information of body surface by using grid-based active stereo, and report preliminary experiments to evaluate validities of the proposed method. By comparing results of our proposed with those of electrocardiogram (ECG), we confirmed sufficient correspondences between peak intervals of inter-frame depth changes measured by the active stereo and R-R intervals measured by ECG. We tried the visualization of the spatial distribution of inter-frame depth change plotted on the 3D shape of chest region. And, the shape change by cardiac beat is mainly found on the left side of the chest region.
