Simulation Of Cinema Intelligent Control System Based On Video

In recent years,4D stereoscopic cinema theater, widely used in all kinds of science and Technology Museum, virtual display field. The key point to be personally on the scene brought by the dynamic 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, it costs lots of time and even not accurate. This paper proposals and implements a novel intelligent analysis method based on video, can automatically analysis the feature points from the video, then computer six dimensional motion parameters of the camera, transmitted to the dynamic seat after intelligent editor.Above all, this paper summarizes the existing video image recognition and tracking algorithm. And analysis of the advantages and disadvantages of them. In the analysis of dynamic theater video intelligence, using optical flow method to detecting and tracking feature points in image sequence. And using the method of image pyramid to reduce error in optical flow computation. After that, to compute the 3D motion parameters of the object through a series of feature points on the target and their corresponding points in the image, using POSIT pose estimation algorithm to solve this problem, and obtain high precision camera pose parameters. Considering the actual effect of experience by the audience, puts forward a nonlinear mapping method of six dimensional motion parameters. In addition to take into account to ensure the safety of the audience when to dynamic seat movement, monitor and adjust the dynamic seat movement parameters on real-time, make it run in safety within a reasonable scope.At last, this paper realized a cinema intelligent control simulation system, including the major control module, digital cinema projection module, control module of dynamic seat platform and the control module of environmental effects. This simulation system can control the cinema movie playback and dynamic seat motion on real-time, and include the related interaction control, meet the cinema intelligent control needs. 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.
