基于GPRS网络的远程图像监控系统

Design of Remote Image Surveillance System Based on GPRS

结合GPRS网络技术和静态图像编解码技术,实现了远程图像监控系统;介绍了图像采集终端和监控中心的组成与设计方法.图像采集终端采集图像传感器的数据,进行快速离散余弦变换压缩,并通过GPRS模块发送到无线网络,监控中心则对从GPRS网络接收到的图像数据进行解压、管理和显示.该系统具有较高的性价比,能够满足一般场合的图像监控要求.

Based on the GPRS network and the still picture compression standard. JPEG, a remote image surveillance system is implemented. The architecture and design of image collection terminal and surveillance center are presented. Image collection terminal acquires image data from the image sensor, compresses them using FDCT, packages the encoded image data and sends them to the GPRS network. Surveillance center is designed to realize the decompression, management and display of the compressed image data received from the GPRS network. The system has low cost and high performance. Therefore, it can meet the general need of image surveillance.
