Abstract

The article presents results achieved during researching the distance measuring method belonging to Depth From Defocus techniques. The method has been developed to determine the shape of the flaccid diaphragm used in the Ventricular Assist Device (VAD). The shape is determined on the basis of distance measured between the CCD sensor plate of the camera and markers located on the flaccid diaphragm. The goal of this paper is to present the influence of the size of the marker on the distance range measured between the camera and diaphragm used in the pneumatic prosthetic heart.
