Abstract

The widespread use of camera systems and the popularity of multimedia sharing websites such as Twitter, Flickr, and YouTube have resulted in an enormous amount of publicly available image and video data. Organizing and browsing such large-scale visual data is, more than ever, a pertinent problem in computer vision. As a subset of this problem, event reconstruction is of great significance because of its potential applications: it can be used for reviewing large-scale sport matches and concert in 3D contexts; experiencing augmented visual tour of historical moments; recovering large areas that were hit by man-made or natural disasters; and to enable crime scene reconstruction for investigators to hunt criminals. In this research project, we aim to investigate methods for organizing, integrating and visualizing visual data to reconstruct historic events. We divide the reconstruction into three stages: 1) collecting and organizing visual data; 2) integrating visual data, including image/video stitching and video sequences recomposing, and 3) visualizing diverse data, which includes exploring different means for 3D reconstruction, projecting visual data onto a 3D environment and designing a navigation system for investigators to understand an event faster and more effectively. After event reconstruction, investigators can further leverage the result for many other things, such as human/objects tracking, behavior analysis, fact-checking, or event understanding. (AU)
