【摘要】：近些年来,随着经济的发展,居民住宅的小区化已成为我国城乡居民的主要居住形式,各式中高档住宅小区遍布城市的各个角落。然而,针对住宅小区的违法犯罪行为也与日俱增,小区安防问题越来越受到人们的重视。小区安防系统有效与否不仅会直接影响居民的生活、生产质量,而且对社会治安也有一定的影响,因此,健全高效的小区安防系统对人们的日常生活来说是举足轻重的。小区监控作为小区安防的重要组成部分,直接决定着安防系统质量,故而,本文对小区监控系统进行了深入研究分析。一般而言,基于应用成本等方面的考虑,传统安防系统以单片机为基础,在扩展性、灵活度等方面存在不足。结合嵌入式系统的性能优势及网络传输技术的广泛应用,本文提出了一种基于ARM的小区远程监控方案,通过在硬件平台上移植相应操作系统完成小区远程监控功能设计。本课题根据目前住宅小区监控设计需求,首先选择ARM11 S3C6410处理器以及USB摄像头作为硬件开发核心,通过在S3C6410处理器上定制移植Linux完成小区监控图像的采集、编码、传输程序设计。利用V4L2完成监控现场图像原始数据的采集,通过多格式编码器MFC对原始数据进行H.264编码得到H.264码流,H.264码流经过实时传输协议RTP完成网络传输,最后通过在客户端移植嵌入式Web服务器boa实现小区监控远程浏览。由于监控系统的最终执行者大都是小区管理人员,必然存在人为因素导致的监控漏洞,降低安防质量。本文在完成小区远程监控的前提下,对动态目标检测进行研究,通过背景减除法的运用,增加目标检测功能。为了减小外界因素对背景模型的影响,本文在背景更新方面做了相应改进,通过对算法参数学习率?的调节,维持背景的稳定与更新。本小区监控系统集成度高、成本低、功耗小,经测试,系统运行可靠、稳定性好,监控画面流畅,目标检测效果良好,满足设计要求。
[Abstract]:In recent years, with the development of economy, residential area has become the main residential form of urban and rural residents in China. However, the illegal and criminal behavior in residential area is increasing day by day, and people pay more and more attention to the security problem of residential district. Whether the residential security system is effective or not will not only directly affect the residents' life and production quality, but also have a certain impact on social security. Therefore, it is very important to improve and improve the security system of residential area for people's daily life. As an important part of community security, community monitoring directly determines the quality of security system. Generally speaking, considering the cost of application, the traditional security system is based on single chip microcomputer, and it has some shortcomings in expansibility and flexibility. Combined with the performance advantage of embedded system and the wide application of network transmission technology, this paper proposes a remote monitoring scheme based on arm, which can complete the design of remote monitoring function by transplanting the corresponding operating system on hardware platform. According to the requirement of residential area monitoring design, the ARM11S3C6410 processor and USB camera are selected as the core of hardware development, and the program design of collecting, coding and transmitting the monitoring image of residential area is accomplished by customizing and transplanting Linux on S3C6410 processor. V4L2 is used to complete the collection of the original data of the monitoring field image, and the H.264 code stream is obtained through the real-time transmission protocol RTP by the multi-format encoder MFC for H.264 coding of the original data. Finally, the remote browsing of residential area monitoring is realized by transplanting the embedded web server boa in the client side. As the final executors of the monitoring system are mostly district managers, there must be monitoring loopholes caused by human factors, which will reduce the quality of security. In this paper, the dynamic target detection is studied on the premise of remote monitoring, and the function of target detection is increased by the application of background subdivision. In order to reduce the influence of external factors on the background model, this paper makes a corresponding improvement in background updating, through the algorithm parameter learning rate? Maintain the stability and renewal of the background. The system has the advantages of high integration, low cost, low power consumption, reliable operation, good stability, smooth monitoring screen, good target detection effect and satisfying the design requirements.
