为实现对家居的实时监控,设计了基于图像处理的安防系统。该系统充分发挥了其硬件性能,核心微处理器通过串口与互补型金属氧化物半导体(CMOS)摄像头进行命令通讯及图像采集;通过图像异常判断程序判断图像是否出现异常;在异常情况下通过彩信模块(MMS)将异常图片发送到指定手机上。该系统的硬件性能实现了图像信息的快速传输,改进的图像处理算法保证了对异常进行准确地判断,为家居安全提供了保障。试验结果表明,该系统能实现对异物入侵状态十分准确的判断,并及时发送报警信息。
Aiming at monitoring empty houses, a security and defense system based on image processing was developed. The microprocessor gets the pictures and communicates with a complementary metal-oxide-semiconductor (CMOS) camera using serial port. If the processed picture is spectral imagery, the picture will be sent to the specific mobile telephone through the multimedia messaging service (MMS). Based on the hardware equipped in the system, the fast image transportation was realized. And by the improved image processing algorithm, the veracity of abnormal detection was guaranteed, the safety of individual' s property was ensured. The test results indicate that the system can effectively find out abnormal condition and rapidly send the warning message.
