为了在网络条件较好的局域网或专用网络上快速开发视频监控系统,提出一种不需要视频编码协议和特殊监控摄像设备的设计方案。该方案在Windows平台上使用普通摄像头进行图像的视频采集,并使用开源的图像处理库程序CxImage对图像帧进行处理,通过网络套接字接口进行传输并在Windows系统上进行显示,并能对监控系统的接入进行身份验证。经过测试该方案能提供稳定的视频监控效果,说明该方法能在网络状态稳定的局域网条件下通过无视频编码协议的方式进行应用,降低了系统开发的复杂度和成本。
For rapidly developing a video surveillance system on LAN or special network which has good condition,a de-sign approach which doesn’t need video encoding protocol and special surveillance camera device is proposed in this paper. In this approach,a normal camera is used in Windows platform to capture the video image,the open source image processing li-brary program CxImage to compress the image frames,and then the data is transfered through network socket interface and dis-played on Windows operating system. It also can verify the identity of accesser which wants to access the surveillance system. The testing result indicates that the approach can provide stable video surveillance effect,and shows that this approach can be used in the mode without video encoding protocol under the condition of LAN with stable network state. This approach decreased the development complexity and cost.
