Basic study on non-contact measurement of cardiac beat by using grid-based active stereo.
We propose a new non-contact measurement of cardiac beat from 3D shape information of body surface by using grid-based active stereo, and basically examine the validity of the proposed method. By simultaneous measurement with our proposed method and ECG, there are sufficient correspondences between peak intervals of inter-frame depth changes measured by our method and R-R intervals measured by ECG.
