Marker Based vs. Natural Feature Tracking Augmented Reality Visualization of the 3D Foot Phantom

In this paper we present novel methods and algorithms for augmenting a foot 3D model in realtime. By overlaying reconstructed anatomical contents onto user’s field of view via an augmented reality visualization platform, the virtual Biomedical Computer Aid Design (BioCAD) objects, appear geo-referenced to the real environment, help physicians and/or students to improve the overall image of the bone condition and anatomical structures of patients. Moreover, we explain the principle of marker and markerless Augmented Reality (AR) and interactive integration of virtual objects in the actual scene by development of a PC and mobile AR applications. In particular, this should be a powerful tool to understand the complex 3D nature and structure of 3D foot bones, joints and assemblies.
