面向动感影院交互控制的视频分析方法

A Video Analysis Method for Live Theater Interactive Control

动感影院给人身临其境体验的关键在于与影片视频结合的互动操控.传统的互动控制方法是根据影片手动编辑动感座椅的运动参数文件,费时费力也不精确.设计并实现了一种基于视频的智能分析方法,可以对视频进行自动分析反求出摄像机参数,经过智能编辑后传递给动感座椅.实验表明,该方法能够快速准确求解影片中摄像机的位姿信息,满足动感影院中播放的实时性,给观众更强的体验感.

The key point to be personally on the scene brought by the live theater is the interaction manipulation combined with the film.Traditional interactive control method is to manually edit the motion parameters file of the dynamic seat from the video,which costs lots of time and even not be accurate.An intelligent analysis method is designed and implemented based on video,which can automatically analyze the feature points from the video,then compute six dimensional motion parameters of the camera,and transmit it to the dynamic seat after intelligent editor.Experimental results show that this method can fast compute pose parameters of camera in the film,satisfying the real-time playback in theater movement,giving the audience a stronger experience feeling.
