【摘要】：监狱是国家的刑罚执行机关，肩负着关押、惩罚和改造罪犯的重任，监狱的安全稳定直接关系着社会安全稳定，视频监控系统是整个监狱安全技术防范系统的核心组成部分，建立完备的监管安全防范体系，搭建和完善覆盖面广、资源共享、综合应用的功能强大监控系统，为监狱安全防范设置一道无形屏障，是我们监狱监控系统建设的首要目标。本文针对传统模拟视频监控系统存在着图像分辨率低、监控范围小和扩展应用能力差等缺点，，研究分析了高清监控和视频智能分析等相关技术，结合某监狱视频监控系统改造项目实际案例，提出了一种基于智能分析技术的高清视频监控系统解决设计方案。论文在监狱需求的基础上对基于智能分析技术的监狱高清视频监控系统进行了分析设计。在概要设计阶段，在介绍监狱高清视频监控系统的基础上，重点设计了智能分析系统的结构和主要模块组成。在详细设计和实现阶段，列举了前端摄像机、传输、存储等系统环节的功能要求，重点设计了智能分析系统的智能分析视频采集、网络传输和存储实现等组成，针对系统的核心部分智能分析模块的背景更新、前景提取、光流计算以及能量计算等技术难点进行详细介绍，同时以这些实现方案为基础，突出分析设计警戒线检测模块、快速移动检测模块以及暴力事件检测模块的实现方案。从而克服了技术局限性，解决了智能分析系统在监狱部署使用问题。论文接着介绍了系统安装后的测试情况，特别列举了智能分析系统的各种应用测试。目前，系统运行正常，达到了预期目标。文章最后对系统的实施作了总结，认为该系统具有良好的社会经济效益和价值，将成为未来监狱监控技术的一个发展方向，并对下一步的工作做了若干思考。
[Abstract]:The prison is the national penalty execution organ, shoulders the heavy responsibility of the imprisonment, the punishment and the reform criminal, the prison safety and stability is directly related to the social security and stability. Video surveillance system is the core part of the whole prison security technology prevention system. It establishes a complete supervision and security prevention system, builds and improves the wide coverage, resource sharing, comprehensive application of a powerful monitoring system. Setting up an invisible barrier for prison security is the primary goal of our prison monitoring system construction. Aiming at the shortcomings of traditional analog video surveillance system, such as low image resolution, small monitoring range and poor ability to expand applications, this paper studies and analyzes some related technologies, such as high-definition surveillance and video intelligent analysis. Based on the actual case of a prison video surveillance system reform project, a solution of high-definition video surveillance system based on intelligent analysis technology is proposed. Based on the demand of the prison, the paper analyzes and designs the high-definition video surveillance system based on the intelligent analysis technology. At the stage of summary design, the paper introduces the high-definition video surveillance system of the prison. The structure and main modules of the intelligent analysis system are mainly designed. In the stage of detailed design and implementation, the functional requirements of the front-end camera, transmission, storage and other system links are listed. The intelligent analysis video collection, network transmission and storage implementation of the intelligent analysis system are mainly designed, aiming at the background update and foreground extraction of the intelligent analysis module of the core part of the system. Optical flow calculation, energy calculation and other technical difficulties are introduced in detail. Based on these implementation schemes, the alarm line detection module is analyzed and designed. The implementation of the fast moving detection module and the violence detection module overcomes the technical limitations and solves the problem of the deployment of the intelligent analysis system in the prison. The paper then introduces the testing situation of the system after installation, especially enumerates the various application tests of the intelligent analysis system. At present, the system runs normally and achieves the expected goal. Finally, the paper summarizes the implementation of the system, thinks that the system has good social and economic benefits and value, will become a development direction of prison monitoring technology in the future, and makes some thoughts on the next work.
