摘　　要：为了解决穿透内网经外网访问另一个内网的问题,提出了一套新型可行的远程视频监控系统解决方案。方案采用客户端/服务器(C/S)的系统模型设计。服务器利用V4L2接口函数控制摄像头采集视频,完成视频转码,并采用NAT-DDNS技术,完成IP地址端口的映射和动态域名的解析。在客户端,创建Iplimage图像结构体变量,实现视频流数据与OpenCV的库函数相结合,并还原和显示帧视频图像。与传统的方案相比,视频观看不受浏览器的限制,且突破局域网,真正的实现客户端穿透内网访问的远程监控。经实验测试,系统图像显示稳定,达到预期效果。To solve the problem of connecting from a network to another network through the external network, an innovative and feasible remote video surveillance system solution is presented. The solution is designed in client / server （ C / S） model. In the server, camera is controlled to capture video by V4L2 interface functions, and video transcoding is completed. The IP address and port are mapped by adopting the NAT-DDNS technology, and dynamic DNS is done. In the client, an Iplimage image structure var- iable is created to combine the video data with the OpenCV library function, reduction of frame video images and display are a- chieved. Compared with the traditional program, the watching of video is avoided from browser limitation, and the client of inside network which is translated to connect the remote monitoring through the outside network by breaking through LAN is really comple- ted. Experimental tests prove that the image display system is stable, and the desired result is accomplished.
