我们提出了一个系统,检索多媒体有关一个人的旅行,使用位置数据捕获的GPS接收器,移动电话或相机。用户在显示在电脑屏幕上的地图上绘制简单的草图,以提交有关其旅行的空间、时间或时空查询。系统将位置数据和图像分割,分析用户绘制的草图,识别查询,并检索相关结果。这些结果与在线地图和使用街景全景渲染的虚拟旅行相结合,形成了多媒体旅行故事。介绍了该系统的现状,并对未来的发展方向进行了总结。
We propose a system for retrieving multimedia related to a person's travel, using location data captured with a GPS receiver, mobile phone or a camera. The user makes simple sketches on a map displayed on a computer screen, to submit spatial, temporal or spatio-temporal queries regarding his travel. The system segments the location data and images, analyzes sketches made by a user, identifies the query, and retrieves relevant results. These results, combined with online maps and virtual tours rendered using street view panoramas, form multimedia travel stories. We present the system's current status and conclude with future directions.
