【摘要】：隨著計(jì)算機(jī)科學(xué)技術(shù)的高速發(fā)展，高清視頻會(huì)議系統(tǒng)在各個(gè)領(lǐng)域逐漸普及，特別是我國(guó)共產(chǎn)黨的十八大精神通過(guò)視頻會(huì)議來(lái)深入貫徹學(xué)習(xí)以來(lái)，我國(guó)的視頻會(huì)議系統(tǒng)進(jìn)入高速發(fā)展階段，更加深入發(fā)展到各行各業(yè)。視頻會(huì)議會(huì)議隨著光纖網(wǎng)絡(luò)的發(fā)展，對(duì)視頻會(huì)議質(zhì)量也越來(lái)越高，而視頻會(huì)議系統(tǒng)想要達(dá)到良好的效果，視頻會(huì)議室的配套設(shè)計(jì)是必不可少的，中小型視頻會(huì)議室，一般部署一臺(tái)高清攝像機(jī)就足夠了，但空間比較大的大型主會(huì)場(chǎng)視頻會(huì)議室往往需要部署2到3個(gè)帶有云臺(tái)功能的高清攝像機(jī)，以便對(duì)會(huì)場(chǎng)進(jìn)行不同角度的拍攝（全景、特寫(xiě)等），這樣就需要工作人員適時(shí)對(duì)攝像機(jī)的云臺(tái)進(jìn)行控制，，而傳統(tǒng)的云臺(tái)控制是通過(guò)云臺(tái)控制鍵盤(pán)來(lái)實(shí)現(xiàn)的，需連接電源線與傳輸線固定在一個(gè)位置來(lái)進(jìn)行操作，使用不夠方便靈活。 傳統(tǒng)的高清視頻會(huì)議系統(tǒng)遙控器都是使用紅外線功能的專(zhuān)用遙控器，但隨著智能平板電腦（Android、IOS）的普及，智能平板電腦的界面清晰易懂，操作簡(jiǎn)單易用，基于智能平板電腦的高清視頻會(huì)議系統(tǒng)遙控器有取代傳統(tǒng)紅外遙控器的趨勢(shì)。經(jīng)過(guò)相應(yīng)的程序開(kāi)發(fā)，可以將視頻會(huì)議系統(tǒng)以及攝像機(jī)的云臺(tái)控制遙控器整合到一個(gè)智能遙控器上，這樣對(duì)視頻會(huì)議系統(tǒng)的控制就更加方便靈活了。 本文的實(shí)現(xiàn)基于CoolView視頻會(huì)議系統(tǒng)，該系統(tǒng)同樣選擇了以遙控器方式操控終端的方案，所不同的是遙控器不再是一個(gè)專(zhuān)用設(shè)備，而是可以在一般移動(dòng)設(shè)備——如手機(jī)、平板上安裝使用的一個(gè)軟件。CoolView視頻會(huì)議系統(tǒng)，作為國(guó)家項(xiàng)目“下一代互聯(lián)網(wǎng)大規(guī)模高清視頻會(huì)議系統(tǒng)應(yīng)用示范”研發(fā)工作的一部分，作者主要負(fù)責(zé)該系統(tǒng)的云臺(tái)控制功能的設(shè)計(jì)與實(shí)現(xiàn)工作，通過(guò)QT與C++開(kāi)發(fā)終端上的本地云臺(tái)控制功能，以及在安卓遙控器上的增加云臺(tái)控制功能模塊，借助WIFI網(wǎng)絡(luò)，以終端遙控器代理程序?yàn)橹薪�，�?shí)現(xiàn)遙控器對(duì)攝像機(jī)云臺(tái)的遠(yuǎn)程控制。 本文已實(shí)現(xiàn)本地云臺(tái)控制以及遠(yuǎn)程云臺(tái)控制功能，并且支持多種云臺(tái)控制協(xié)議，已在CoolView視頻會(huì)議系統(tǒng)中使用，為用戶提供便捷的控制服務(wù)，具有良好的現(xiàn)實(shí)意義。
[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.
