摘要:
针对传统基于PC网络摄像机的稳定性差、效率低以及系统结构复杂等问题,本文提出了基于DM642的高速网络摄像机的设计方案.通过对流媒体协议的研究,对基于DM642的高速网络摄像机进行硬件和软件设计,实现了视频采集、视频信号处理、网络实时传输、过程控制等功能的集成.结果表明,使用DM642专用视频处理芯片设计的网络摄像机可以显著提高网络摄像机的整体效率和性能,较好地解决传输速率与图像质量之间的矛盾,同时也利于产品化和升级.
Abstract:
According to the traditional Web-Camera based on the PC whose stability is bad,efficiency is low as well as the system structure is complicated and so on.This paper presents a high speed Web-Camera’s design proposal based on the DM642.Through the research of the streaming media protocol,the hardware and software design of high speed Web-Camera based on DM642,the integration of video capture,video signal processing,network real-time transmission and process control are realized.The result shows that using DM...
