Abstract
Denne rapport beskriver analyse, design og implementering af en prototypeløsning til et augmented reality (AR) museum – en oplevelse, hvor digitale 3D-elementer lægges oven på den fysiske verden i realtid. Systemet er opbygget som moduler i PAVE (Parallel Architecture for Visual Effects), en software-ramme der fordeler visuelle beregninger på flere processorer. Derfor skalerer ydeevnen på multiprocessor-pc’er; vi målte en forbedring på 54 % ved at gå fra én til to processorer. Prototypen udnytter 3D-grafikhardware (grafikkort) til visualisering i realtid og kan knytte dynamiske visuelle effekter til 3D-objekter. På testmaskinen kørte systemet i realtid med en minimum billedfrekvens på 9,1 billeder i sekundet. Rapporten gennemgår den overordnede systemarkitektur, de forbedringer der blev lavet i PAVE, samt de algoritmer, der opfylder kravene til et AR-museum.
This report presents the analysis, design, and implementation of an augmented reality (AR) museum prototype—an experience where digital 3D elements are overlaid on the physical world in real time. The system is built as modules within PAVE (Parallel Architecture for Visual Effects), a software framework that distributes visual computations across multiple processors. As a result, performance scales on multiprocessor PCs; we measured a 54% improvement when moving from one to two processors. The prototype uses 3D graphics hardware (a graphics card) for real-time visualization and can attach dynamic visual effects to 3D objects. On the test machine, the system ran in real time with a minimum frame rate of 9.1 frames per second. The report outlines the overall system architecture, the enhancements made to PAVE, and the algorithms selected to meet the requirements of an AR museum.
