A Projection-based Medical Augmented Reality System

Abstract

In this paper, we present a projection-based medical augmented reality (AR) system for craniofacial application. With the aid of image registration and geometrical correction, the deformation of the projected image on a curved surface like cheek or forehead can be successfully recovered. From the experimental result, it is shown that the overlapped target region is up to 98% after the correction process and this demonstrates the effectiveness of the proposed system.
