Abstract

This paper presents a complete solution for the creation and manipulation of the 3D representationof a human face model using off the shelf components. First, the 3D model is obtained bymeans of a structured light system that is calibrated using only the vanishing points extracted from asimple planar surface. Then, an immersive interaction technique is used to manipulate the 3D model.The interaction tool is located in 3D space using a fuzzy technique with the advantages of a lowmemory usage, real-time operation and low positioning errors as compared to classical solutions. Experimentalresults including accuracy evaluation of the reconstruction and of the interaction tool arepresented. The resulting system can find applications in expression based human-computer interaction,virtual assisted cosmetic surgery, as well as in the teleconferencing, being in line with the currenttrends of intelligent user interfaces.

Summary

Introduction

The creation, visualization and interaction with 3D models are crucial steps in many applications. The digitized 3D world must be readily accessible to human users, ergonomic human-computer interfaces are necessary. Traditional interaction devices such as the keyboard or the mouse are not the most appropriate tools considering that, in daily practice, 3D objects are approached in a much more flexible way. We describe here a complete solution for the creation and manipulation of the 3D representation of a human face using off the shelf components. The 3D model is created using active shape acquisition techniques. The face model is manipulated using an immersive technique based on a hand-held device that produces a realistic human-computer interaction. Active shape acquisition techniques for 3D model creation. Shape acquisition techniques can be classified in two groups: passive and active techniques
