我们提出了一种新的方法来渲染和合成视频增强现实。我们着重计算有限孔径透镜引起的景深的物理正确结果。为了正确模拟光传输,使用光线跟踪,并在一个单一的通道与差分渲染相结合,以组成最终的增强视频。图像完全在GPU上渲染,因此可以以高质量的交互式帧速率生成增强视频。我们的方法在飞行中运行,不需要视频后处理。此外,我们评估了用户体验与我们的渲染系统的假设,增强现实中的景深效果增加了合成视频的真实感。30名用户的结果显示,90%的人认为视频的景深更加逼真。
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.
