我们提出了一个新的电影地图的步行者,合成街道步行意见沿着路线的步行者在一个地区。我们从某个地区的街道步行者的角度获得了一些全方位的视频(例如。京都站周围1 km^2 $),然后执行SLAM以获得关键视频帧的相机姿态,其中使用参考点将坐标调整到该区域的地图。为了在交叉点处切换视频,我们使用摄像机位置来识别视频交叉点的帧。我们使用视觉特征匹配来细化交叉帧。最后,我们合成移动路线的意见,通过切换全向视频与对准的方向的相机。实验结果表明,该方法能够准确识别出相交帧,并在相交处实现视频的平滑切换。
We present a new movie map for walkers that synthesizes street walking views along routes for walkers in an area. We acquired a number of omnidirectional videos from the perspectives of walkers of streets in a certain area (ex. $1km^2$ around Kyoto Station), then perform SLAM to obtain camera poses of key video frames with the coordinates adjusted to the map of the area using reference points. In order to switch one video to another at intersections, we identify the frames of video intersection using camera locations. We refine the intersection frames using visual feature matching. Finally, we synthesize moving route views by switching omnidirectional videos with alignment of the direction of the cameras. The result shows that our method can precisely identify the intersection frames, and generates smooth switching of videos at the intersection.
