Film and television industry cloud exhibition design based on 3D imaging and virtual reality

The three-dimensional virtual scene can provide users with a visual three-dimensional virtual environment, with various multimedia channels such as sound, video, force feedback equipment, etc., to bring users a completely immersive interactive experience. This paper introduces 3D imaging and virtual reality technology in the film and television industry cloud exhibition, and develops a virtual display platform. First of all, this paper divides the registration into two processes: camera calibration and joint calibration of the camera and laser scanner based on the calibration results. Camera calibration can determine the plane model of the calibration board in the camera coordinate system, and the joint calibration uses the RANSAC algorithm to extract the point cloud of the plane model of the calibration board, and then optimizes the distance between the points in the plane model point cloud and the corresponding plane in the camera coordinate system Find the optimal transformation between the two sets of data, and then calculate the registration relationship between the point cloud and the image. Secondly, this article conducts a demand analysis of the film and television industry cloud exhibition platform based on virtual reality technology, including the business goals set by the platform, platform system analysis, overall design, and system operating environment and configuration requirements. This model provides a feasible solution for the visual interaction of the cloud exhibition design of the film and television industry.     

基于影视剧《长安十二时辰》管窥盛唐男装

《长安十二时辰》是一部唐代背景古装剧,其男装服饰设计基于历史,可为戏服研究所借鉴。文章基于《长安十二时辰》影视、小说及相关文史资料,运用图像学原理,对该剧的影视男装进行探析。研究认为:《长安十二时辰》中的男装设计可圈可点,无论是款式、色彩还是图案甚至服饰搭配都较为严格遵循唐代服饰制度,整体上符合唐代服饰特点;《长安十二时辰》中的部分服饰细节上仍有错误,如李必冠帽的使用上,但瑕不掩瑜;《长安十二时辰》中胡服的设计和使用在颜色和图案乃至穿用人群上都较为灵活,表现了唐代文化的兼容并蓄。     

Impacts of new technologies on media usage and social behaviour in domestic environments

Technological infrastructure at home is changing continuously and is becoming increasingly interconnected. Media devices, including the TV set, provide access to the Internet and offer manifold opportunities to consume media on demand. Additionally, personal devices, such as smartphones, also enable flexible consumption and sharing of media. Questions about how these technologies change the user's media usage and how these changes affect the social structure of a household, however, remain largely unanswered. In order to gain insight into the adoption of new technologies into daily routines, we explored these changes in respect of people's media usage in a qualitative long-term Living Lab study. We will present findings regarding personal routines, flexible integration of new devices into existing practices, influences on households as social systems and related issues in device access and collective use. We will highlight potentials and conflicts regarding device shifts and roles; restrictions in device access; social influences in the living room; and individual changes in media consumption.

基于北斗卫星的广播电视授时系统研究

在广播电视系统中,标准时间占有重要的位置,是安全播出的前提条件.目前,广播电视中心常利用GPS授时来获取标准时间,GPS授时存在手段单一和我国没有自主控制权两方面问题.本系统基于我国自主研发的北斗卫星获取标准时间,并与本地实验室时间进行校准,实现全台时间同步.目前北斗卫星在广播电视系统中的应用基本上还是空白.因此,此项研究对改变国外的卫星授时系统垄断我国市场的状况,保证我国的信息安全,具有重要意义.
