随着数字图像处理技术的日益成熟和通信带宽的日益提高,以应用数字图像处理技术为核心的远程图像监控系统已经成为一种发展趋势。针对现代化大型工厂的生产和安全对远程、实时监控的需要,设计了一种基于DSP技术的远程监控系统,本文简述了该系统的硬件组成,重点介绍了监控系统的软件设计和实现。该系统可通过局域网、互联网、等实时传送现场图像、声音以及各种监控数据,具有视频压缩、解码、网络传输、图像储存、图像索引回放、摄像机远程控制以及图像移动侦测报警等功能。
With the maturing of digital image processing technology and the increasing communication bandwidth, remote image monitoring system using digital image processing technology as the core has become a trend. In view of the need of remote and real-time monitoring of the production and safety of modern large-scale factories, a remote monitoring system based on DSP technology is designed. This paper briefly describes the hardware components of the system and focuses on the software design and implementation of the monitoring system. The system can send live images, sound and various monitoring data in real time through LAN, Internet, etc. It has such functions as video compression, decoding, network transmission, image storage, image index playback, camera remote control and image motion detection alarm.
