论文摘要
我们提出了一个新的电影地图系统，并具有用于探索城市的界面。该系统由四个阶段组成；获取，分析，管理和互动。在收购阶段，全向视频沿着目标地区的街道拍摄。视频的框架位于地图上，检测到交叉点，并分割视频。随后生成交叉点的转弯视图。通过在某个区域的指定运动之后连接视频片段，我们可以更好地查看街道。该接口可以轻松探索目标区域，并且可以在视图中显示虚拟广告牌。在用户可以自由移动和探索以找到地标的情况下，我们进行了用户研究，以将我们的系统与GSV进行比较。实验表明，我们的系统比GSV具有更好的用户体验。
We propose a new Movie Map system, with an interface for exploring cities. The system consists of four stages; acquisition, analysis, management, and interaction. In the acquisition stage, omnidirectional videos are taken along streets in target areas. Frames of the video are localized on the map, intersections are detected, and videos are segmented. Turning views at intersections are subsequently generated. By connecting the video segments following the specified movement in an area, we can view the streets better. The interface allows for easy exploration of a target area, and it can show virtual billboards of stores in the view. We conducted user studies to compare our system to the GSV in a scenario where users could freely move and explore to find a landmark. The experiment showed that our system had a better user experience than GSV.
