摘要

本文提出了一种视频回放系统,允许用户将视场扩展到原始视频帧中不可见的周围环境,任意改变视角,并在视频回放过程中以增强现实的方式看到叠加的兴趣点(poi)数据。该处理主要包括两个步骤:第一步,客户端上传视频到GeoVideo引擎,GeoVideo引擎提取地理元数据并返回给客户端;第二步,客户端向服务器请求poi,然后客户端使用poi渲染视频。

Augmented and interactive video playback based on global camera pose
This paper proposes a video playback system that allows user to expend the field of view to surrounding environments that are not visible in the original video frame, arbitrarily change the viewing angles, and see the superimposed point-of-interest (POIs) data in an augmented reality manner during the video playback. The processing consists of two main steps: in the first step, client uploads a video to the GeoVideo Engine, and then the GeoVideo Engine extracts the geo-metadata and returns them back to the client; in the second step, client requests POIs from server, and then the client renders the video with POIs.
