Research on Mine Video Surveillance System Based on Embedded System and Motion Detection

摘要:

针对传统模拟信号监控的不足,设计了一种基于S3C6410硬件平台、Linux2.6软件平台、H.264标准及运动检测算法和WIFI无线网络传输的井下视频监控系统；针对井下监控背景基本不变,采用H.264图像压缩算法以及改进的单高斯模型运动检测算法；并提出了整体监控软件的设计方案；最后通过PSNR、压缩比、压缩时间以及压缩速率等参数对算法进行了实验,实验结果表明:该系统能在较低的编码速率上实现较好的成像质量,具有较高的压缩质量,可满足实时编码需求。

Abstract:

Aiming at the disadvantage of traditional analog monitor, a mine video surveillance system is designed based on S3C6410 hardware platform, Linux 2.6 software platform, H.264 coding and WIFI wireless. For the background is essentially the same, this paper use of H.264 sigle Gaussian moving image compression algorithm and proposed the code optimization methods. And proposed the scheme of system software. Finally, through the PSNR, compression ratio, compression time and rate to verify the algorithm. The experimental results show:This system can realize better quality of image on lower speed, has higher coding rate and can satisfy the real time encoding demand.
