基于Motion算法移动图像监控系统的设计与实现

摘要

针对入室盗窃、非法入侵等违法犯罪行为的预防和调查取证,提出了一种基于Motion算法移动图像监控系统.该系统通过USB图像采集模块采集图像,开源的Motion算法实现了对采集到的图像进行比较,当相邻图像差异超过设定的阈值则判定为移动图像,RT5350处理中心将移动图像进行存储同时通过串口向STM32发送开启报警命令来开启报警,当超过设定时间间隔未检测到移动图像则通过串口向STM32发送关闭报警命令来关闭报警,Web客户端通过基于HTTP协议的Lighttpd服务器查看RT5350处理中心存储的图像.经多次测试系统运行稳定并且采集到移动图像时能开启报警,同时能通过Web客户端查看存储的移动图像,当超过设定的时间间隔未检测到移动图像时能关闭报警.%For burglary, illegal intrusion and other criminal acts of prevention and investigation evidence,a mobile image monitoring system based on Motion is proposed.The system collects the images through USB image acquisition module ,the open source Motion algorithm has realized the comparison of the collected images,when the difference of the adjacent image is over the set threshold judged to move the image,RT5350 processing center will store the mobile image at the same time send the command of open alarm to STM32 to open alarm through the serial port ,when the mobile image is not detected over the set time interval send the command of close alarm to STM32 to close alarm through the serial port , Web client through Lighttpd server which based on HTTP protocol view the image which stored in the RT5350 processing center. After many times test the system runs stably and can open the alarm when collect mobile images, at the same time the Web client can view the mobile image which has been stored,when the mobile image is not detected over the set time interval can close alarm.
