摘　　要：设计了基于互联网通信技术的摄像机舵机二自由度自由转动远程控制系统。该控制系统以Raspberry Pi微型计算机为控制核心,实现摄像机上下和左右二自由度灵活转动,并采用互联网传输技术对摄像机采集的图像信息和摄像机转动控制信息进行实时传输,实现远程控制。系统运行时,图像信息和摄像机云台的控制信息以搭建在主控制器上的Web服务器为枢纽,实现移动客户端与系统的数据交互和摄像机视觉系统的远程控制。Web服务器的搭建应用了Flask微框架,Web前端应用了HTML、CSS、JavaScript和Ajax技术。实验样机验证,实现了摄像机视野范围的客户端远程监控,并实现了用户在客户端对摄像机视野范围二自由度灵活调整的远程控制,达到了预期的控制效果。Considering limited visual range of fixed camera,a remote control system of flexibly rotating camera in two degrees of freedom is proposed based on the Internet communication technology. The Raspberry Pi single board computer is the core of the control system,it can make the camera to realize two degrees of freedom flexible rotation. The one degree of freedom is the up and down,and the other is the left and right. The image information collected by the camera and the camera rotation control information are transmitted in real time by using the Internet transmission technology.When the system is operating,the image information and the control information of the camera are transmitted by the Web server built on the main controller to realize the data interaction between the mobile client and the system,furthermore to realize the remote control of the camera vision system. The Web server is built using the Flask microframework,and HTML,CSS,JavaScript,and Ajax are used to design the Web front-end. Through the experimental prototype,the client remote monitoring of the camera’s field of view is realized,the remote control of the flexible adjustment of the two degrees of freedom of the camera’s field of view is also realized,and the desired control effect is achieved.
