摘要

由于视频捕捉技术的快速发展,每天都有越来越多的旅游视频被捕获,这给元数据的组织和关联带来了挑战。本文提出了一种新的旅游视频标注导航系统。在视频中放置注释是困难的,因为需要跟踪摄像机的运动。由于媒体的顺序性,常规视频的导航也具有挑战性。为了克服这些挑战,我们引入了一个将视频注册到地理参考3D模型并分析视频内容的系统。我们还介绍了一种新的视频注释显示调度算法。我们在自动注释视频和基于地图的视频浏览应用程序中显示结果。我们的用户研究表明该系统是非常有用的。

Annotating and navigating tourist videos
Due to the rapid increase in video capture technology, more and more tourist videos are captured every day, creating a challenge for organization and association with metadata. In this paper, we present a novel system for annotating and navigating tourist videos. Placing annotations in a video is difficult because of the need to track the movement of the camera. Navigation of a regular video is also challenging due to the sequential nature of the media. To overcome these challenges, we introduce a system for registering videos to geo-referenced 3D models and analyzing the video contents. We also introduce a novel scheduling algorithm for showing annotations in video. We show results in automatically annotated videos and in a map-based application for browsing videos. Our user study indicates the system is very useful.
