Virtual automatic cinematography is of great importance to lower the professional threshold for filming and reduce space cost and labor cost of shooting.In this paper it was proposed to use data-driven automatic cinematography technology with aesthetic assessment technology to build an automatic cinematography system for cloud performing arts.Firstly,extracted character joint point in the real video,and then the main actors were judged and the toric space was constructed.Secondly,the feature estimation network was used to extract the camera features and character features,and the motion parameters of the camera were calculated through camera motion extraction gating network and camera trajectory prediction network.After that,these parameters controlled the virtual camera in Unity3D to generate camera trajectory and video.Then through the aesthetic assessment model,the overall aesthetic score of the picture was marked and the main composition pattern was judged.And the system selected the camera position with the best performance.Finally,the user could get the track of camera and the video captured by the chosen camera on Wechat MiniProgram.The virtual environment based on the auditorium of Communication University of China and Xixiakou Theater of Weihai,Rongcheng was taken as an example to demonstrate the effect of the intelligent shooting system.
