Social Snapshot: A System for Temporally Coupled Social Photography

摘要

Social Snapshot is a system for temporally coupled social photography. It leverages computer graphics and computer vision advances, along with the ubiquity of consumer-level programmable cell phone cameras, to actively acquire time-varying spatial data. Social Snapshot enables spatiotemporal 3D photography using commodity devices, assisted by their auxiliary sensors and network functionality. The end result is a set of locally optimized 2.5D meshesȁ4;one for each input photographȁ4;created with a novel mesh generation technique. Although these models could be globally inconsistent, the navigation model uses the recovered camera-pose information and view interpolation techniques to smoothly navigate the reconstruction interactively.
