Given an Internet photo collection of a landmark, we compute a 3D time-lapse video sequence where a virtual camera moves continuously in time and space. While previous work assumed a static camera, the addition of camera motion during the time-lapse creates a very compelling impression of parallax. Achieving this goal, however, requires addressing multiple technical challenges, including solving for time-varying depth maps, regularizing 3D point color profiles over time, and reconstructing high quality, hole-free images at every frame from the projected profiles. Our results show photorealistic time-lapses of skylines and natural scenes over many years, with dramatic parallax effects.

互联网照片的 3D 延时重建

给定一个地标的互联网照片集，我们计算一个 3D 延时视频序列，其中虚拟相机在时间和空间上连续移动。虽然之前的工作假设使用静态相机，但在延时摄影期间添加相机运动会产生非常引人注目的视差印象。然而，实现这一目标需要解决多项技术挑战，包括解决时变深度图、随时间调整 3D 点颜色配置文件以及从投影配置文件中的每一帧重建高质量、无孔的图像。我们的结果显示了多年来天际线和自然场景的逼真延时，具有戏剧性的视差效果。
