基于Web图像监控系统的设计与实现

Design and implementation of the image surveillance system based on Web

为了加快图像的传输速度,提出了一种基于Web的图像监控系统。该系统使用了基于Lighttpd的Web服务器与Web客户端建立连接并传输数据来加快图像数据的传输,另外对图像进行选择性存储,即只采集像素发生了变化的图像,减少存储的数锯,从而加快数据的传输。系统通过USB图像采集模块采集图像,由动态图像检测算法对图像进行处理并存储,客户端通过Web服务器获取存储的图像。

To speed up the transfer speed of the image, this paper presents a Web-based image surveillance system. The system uses a Web- based Lighttpd server to establish connection with the Web client and transfer data to speed up transmission of image data, in addition to op- tionally storing images that only the image pixel is changed to reduce the number of stored data thereby accelerating data transmission. The sys- tem acquires images via USB image acquisition module, and processes and stores images using the dynamic image detction algorithm. The cli- ent obtains the stored images through Web server.
