中文摘要：

介绍了一种基于IP-VPN网络的构建眼底照相机远程操控系统的方案，系统采用C／S模式，其中视频服务器采用了CCD摄像头、H.264视频实时压缩采集卡，快速地完成视频采集、压缩编码发送。同时，视频服务器通过RS232串口通信控制步进电机动作。客户端通过WinSock编码技术实现与视频服务器通信，进而远程控制眼底照相机操作。实验结果表明，这一方案能满足眼底图像实时显示和远程操控眼底照相机的功能。

英文摘要：

An solution to construct remote operation and control system of fundus camera based on IP-VPN internet has been introduced. The system uses C/S mode, and the video server uses CCD camera, H.264 video real-time compression and collection card, it can finish video collection, compression encoder and sending fast. Meanwhile, the video server controls the operation of stepping motor through RS232 serial port communication. The client computer uses WinSock to complete the communication with the video server,and then controls the operation of the remote fundus camera. Results show that it meets the function of fundus image real-time showing and remote operation and control of fundus camera.
