高清视频会议终端云台控制的设计与实现
发布时间：2018-08-01 16:59
【摘要】：随着计算机科学技术的高速发展，高清视频会议系统在各个领域逐渐普及，特别是我国共产党的十八大精神通过视频会议来深入贯彻学习以来，我国的视频会议系统进入高速发展阶段，更加深入发展到各行各业。视频会议会议随着光纤网络的发展，对视频会议质量也越来越高，而视频会议系统想要达到良好的效果，视频会议室的配套设计是必不可少的，中小型视频会议室，一般部署一台高清摄像机就足够了，但空间比较大的大型主会场视频会议室往往需要部署2到3个带有云台功能的高清摄像机，以便对会场进行不同角度的拍摄（全景、特写等），这样就需要工作人员适时对摄像机的云台进行控制，，而传统的云台控制是通过云台控制键盘来实现的，需连接电源线与传输线固定在一个位置来进行操作，使用不够方便灵活。 传统的高清视频会议系统遥控器都是使用红外线功能的专用遥控器，但随着智能平板电脑（Android、IOS）的普及，智能平板电脑的界面清晰易懂，操作简单易用，基于智能平板电脑的高清视频会议系统遥控器有取代传统红外遥控器的趋势。经过相应的程序开发，可以将视频会议系统以及摄像机的云台控制遥控器整合到一个智能遥控器上，这样对视频会议系统的控制就更加方便灵活了。 本文的实现基于CoolView视频会议系统，该系统同样选择了以遥控器方式操控终端的方案，所不同的是遥控器不再是一个专用设备，而是可以在一般移动设备——如手机、平板上安装使用的一个软件。CoolView视频会议系统，作为国家项目“下一代互联网大规模高清视频会议系统应用示范”研发工作的一部分，作者主要负责该系统的云台控制功能的设计与实现工作，通过QT与C++开发终端上的本地云台控制功能，以及在安卓遥控器上的增加云台控制功能模块，借助WIFI网络，以终端遥控器代理程序为中介，实现遥控器对摄像机云台的远程控制。 本文已实现本地云台控制以及远程云台控制功能，并且支持多种云台控制协议，已在CoolView视频会议系统中使用，为用户提供便捷的控制服务，具有良好的现实意义。
[Abstract]:With the rapid development of computer science and technology, high-definition video conferencing system has been gradually popularized in various fields, especially since the spirit of the 18th National Congress of the Communist Party of China has been deeply studied through video conferencing. China's video conferencing system has entered a high-speed stage of development, more in-depth development to a variety of industries. With the development of fiber optic network, the quality of video conference is becoming higher and higher. If the video conference system wants to achieve good results, the design of video conference room is essential. Generally, one high-definition camera is enough, but large video conference rooms with larger space often need to deploy two to three high-definition cameras with cloud head functions to film the venue from different angles (panoramic view). This requires the staff to control the head of the camera at the right time, while the traditional control of the cloud head is realized by the keyboard of the control of the cloud head. It is necessary to connect the power line with the transmission line and fix it in the same position to operate. It is not convenient and flexible to use. The traditional remote controller of high-definition video conference system is a special remote controller with infrared function, but with the popularization of the intelligent tablet computer (Android iOS), the interface of the intelligent tablet computer is clear and easy to understand, and the operation is easy to use. The remote controller of high-definition video conference system based on intelligent tablet computer has the tendency to replace the traditional infrared remote controller. Through the corresponding program development, the video conference system and the remote controller of the video camera can be integrated into an intelligent remote controller, so the control of the video conference system is more convenient and flexible. The implementation of this paper is based on the CoolView video conference system, which also chooses the scheme of controlling the terminal by remote control. The difference is that the remote controller is no longer a special device, but can be used in general mobile devices, such as mobile phones. A software. CoolView videoconferencing system is installed on the tablet as part of a national project, "demonstration of the application of the next generation Internet large-scale high-definition videoconferencing system". The author is mainly responsible for the design and implementation of the control function of the cloud head of the system, through QT and C to develop the local control function of the cloud head on the terminal, and to add the module of the control function of the cloud head on the remote controller of Android, with the help of the WIFI network. Terminal remote control agent program is used to realize remote control of camera head. This paper has realized the control function of local cloud head and remote cloud head, and has supported many kinds of cloud head control protocols. It has been used in CoolView video conference system and provides convenient control service for users. It has good practical significance.
