Augmenting Physical Avatars Using Projector-Based Illumination, Anselm Grundhöfer
Sprache des Titels:
Bringing virtual characters to life is one of the great challenges in computer graphics. While there were tremendous advancements in capturing, animating, and rendering realistic human faces in the past decade, displaying them on traditional screens conveys only a limited sense of physical presence. Animatronic figures or robotic avatars can bridge this gap. However, in contrast to virtual face models, reproducing detailed facial motions on an animatronic head is highly challenging due to physical constraints. Although steady progress in creating highly sophisticated robotic heads that strive to recreate convincing facial motions can be observed, for example those in Disney World?s Hall of Presidents or ?Geminoids?, these achieve only limited expressiveness when compared to a real human being.
In my presentation I will present a processing pipeline for augmenting physical avatars using projector-based illumination, significantly increasing their expressiveness by superimposing high-frequency details using projection based illumination. Besides a detailed description of the different processing steps of the system, I'll present an overview of the variety of advanced projection systems the Walt Disney Company uses in current theme park installations to enhance the visitor's sense of immersion.
