【摘要】：隨著監(jiān)獄各項監(jiān)控硬件的普及，監(jiān)獄視頻監(jiān)控進入了智能化和網(wǎng)絡(luò)化的模式。通過網(wǎng)絡(luò)傳輸?shù)姆绞綄⒈O(jiān)獄各大場所的監(jiān)管安全信息數(shù)據(jù)聯(lián)系起來，使監(jiān)獄內(nèi)外各大執(zhí)法辦公場所均可以查看視頻監(jiān)控數(shù)據(jù)，給今后的監(jiān)管安全提供了保證，并大大方便了警察對罪犯關(guān)押現(xiàn)場的實時管理。但傳統(tǒng)有線視頻監(jiān)控的集成成本高、后期維護量大、位置布局工序煩雜等嚴(yán)重制約了監(jiān)控的便利性，已無法滿足監(jiān)獄監(jiān)控?zé)o死角的需求，因此本文提出了基于ARM9內(nèi)核的S3C2440處理器為核心的嵌入式無線監(jiān)控應(yīng)用解決方案。整個方案由圖像采集前端和視頻監(jiān)控端（即PC機監(jiān)控軟件）兩部分組成，前端攝像頭通過V4L2技術(shù)實現(xiàn)圖像數(shù)據(jù)采集，經(jīng)H.264壓縮算法將數(shù)據(jù)打包，再經(jīng)無線網(wǎng)絡(luò)發(fā)送至PC應(yīng)用端，從而建立一個完整的監(jiān)獄無線視頻監(jiān)控平臺，對罪犯實時現(xiàn)場信息進行靈活地查詢或篩選，為掌握罪犯在監(jiān)獄的動態(tài)狀況提供強大支持。 本文主要重點介紹嵌入式硬件環(huán)境的搭建和應(yīng)用層面智能識別的設(shè)計，硬件環(huán)境搭建包括有bootload的移植，Linux系統(tǒng)的移植，根文件系統(tǒng)的制作等，還包括了無線網(wǎng)卡模塊在嵌入式環(huán)境下的移植工作。而應(yīng)用層面設(shè)計包括V4L2的圖像數(shù)據(jù)采集，H.264壓縮算法，SDL函數(shù)顯示設(shè)計和智能識別等。 監(jiān)獄無線視頻監(jiān)控的應(yīng)用，對監(jiān)獄信息化實現(xiàn)監(jiān)控安全萬無一失具有重要意義：一是罪犯現(xiàn)場信息可以得到實時更新和查詢，二是對于突發(fā)事件能夠及時發(fā)現(xiàn)，，大大增強警察應(yīng)急效率。
[Abstract]:With the popularization of the prison monitoring hardware, the prison video surveillance has entered the mode of intelligence and networking. Through the way of network transmission, the prison security information data of various places are linked together. Make the prison inside and outside the law enforcement office can view video surveillance data, for the future supervision and security to provide a guarantee. It greatly facilitates the real-time management of the crime scene. But the integration cost of traditional cable video surveillance is high, the later maintenance amount is large, the location layout process is troublesome and so on, which seriously restricts the convenience of monitoring. The need for prison surveillance has not been met. Therefore, this paper proposes an embedded wireless monitoring application solution based on S3C2440 processor based on ARM9 kernel. The whole solution is composed of image acquisition front end and video monitor terminal (. That is, PC monitoring software) is composed of two parts. The front-end camera uses V4L2 technology to realize image data acquisition, the data is packed by H.264 compression algorithm, and then sent to PC application via wireless network. In order to establish a complete prison wireless video surveillance platform, the real-time scene information of criminals can be queried or filtered flexibly, which can provide powerful support to grasp the dynamic situation of criminals in prison. This paper mainly introduces the construction of embedded hardware environment and the design of intelligent recognition in application level. The hardware environment construction includes the transplantation of bootload system. The production of root file system also includes the transplantation of wireless network card module in embedded environment, and the application layer design includes the image data acquisition H.264 compression algorithm of V4L2. SDL function display design and intelligent recognition. The application of prison wireless video surveillance is of great significance to the security of prison information. Firstly, the information on the scene of criminals can be updated and queried in real time. Second, the emergency can be found in time, greatly enhance the police emergency efficiency.
