Kurzfassung englisch:
We present a novel method for rendering and compositing video in augmented reality. We focus on calculating
the physically correct result of the depth of field caused by a lens with finite sized aperture. In order to correctly
simulate light transport, ray-tracing is used and in a single pass combined with differential rendering to compose
the final augmented video. The image is fully rendered on GPUs, therefore an augmented video can be produced at
interactive frame rates in high quality. Our method runs on the fly, no video postprocessing is needed. In addition
we evaluated the user experiences with our rendering system with the hypothesis that a depth of field effect in
augmented reality increases the realistic look of composited video. Results with 30 users show that 90% perceive
videos with a depth of field considerably more realistic.
