摘要
介绍了一种基于多媒体处理器DM643的高清晰度网络摄像机硬件设计方案,该方案应用了高分辨率CMOS图像传感器,图像分辨率最高可达三百万像素,采用了以太网供电等技术,便于工程安装。通过嵌入式软件编程,实现了H.264、MPEG4等多种视频编码算法,以及图像分析和识别等功能,可广泛用于各种视频监控和视频分析场合。
A hardware design of IP camera system is introduced, in which high definition CMOS sensor is used and the resolution about 3 megapixels is supported. The PoE power supply technique is introduced in the IP camera for easy to mount. The design has implemented the functions as H.264,MPEG4 video encoding and video analysis by embedded software program. It can be used in various applications such as video surveillance and video analysis.
