【摘要】：隨著時代發(fā)展,人們對生活質(zhì)量的要求也在不斷提高。人們普遍希望生活在安全、舒適、和諧的環(huán)境中,由此,超高清視頻監(jiān)控成為目前關(guān)注度較高的研究問題。大家希望足不出戶,便能從視頻監(jiān)控中得知事情的過程,獲知高清攝像信息。在此背景下,本文開發(fā)了以ARM cotex-A53的三星S5P6818芯片的嵌入平臺為核心,設(shè)計基于Android 5.1的分辨率達3840×2160P的UHD H.265超高清高性能遠程無線監(jiān)控平臺。論文深入探討了智能家居以及有關(guān)的監(jiān)控體系的發(fā)展狀況及趨勢,同時針對Android系統(tǒng)的開發(fā)環(huán)境和相關(guān)演變問題進行簡要的論述,然后詳細介紹了Binder IPC機制以及Camera系統(tǒng)架構(gòu)設(shè)計,具體分析了Binder IPC的機制情況以及Binder IPC機制通信過程,全方位介紹了Camera的系統(tǒng)層析結(jié)構(gòu)、應(yīng)用設(shè)計以及Camera預(yù)覽數(shù)據(jù)流的設(shè)計,針對Android系統(tǒng)環(huán)境之中對應(yīng)的Binder IPC機制和有關(guān)的Camera子系統(tǒng)的基礎(chǔ)框架開展系統(tǒng)的論述,為后文的有關(guān)分析進行良好的鋪墊。第四章詳盡說明了UHD分辨率H.265編碼遠程監(jiān)控的實現(xiàn),其中重點研究了UHD像素攝像頭驅(qū)動設(shè)計、Camera Server總體設(shè)計和H.265實時碼流傳輸?shù)脑O(shè)計,通過對系統(tǒng)的調(diào)試與安裝,探討該系統(tǒng)的實際達成,從而使得針對HAL驅(qū)動的編制得到完整細致的論證,同時得出了配套的參數(shù)、結(jié)果和具體的調(diào)試操作。通過系統(tǒng)的安裝與調(diào)試,驗證了一般條件下能較好地實現(xiàn)數(shù)據(jù)的傳輸監(jiān)控。該方案解決了原有系統(tǒng)的局限性,提高了系統(tǒng)的穩(wěn)定性、分辨率,在一定程度上解決了目前遠程監(jiān)控系統(tǒng)存在的不足。論文實現(xiàn)了超高清分辨率H.265遠程監(jiān)控功能,整個系統(tǒng)性能基本符合預(yù)期目標。論文的研究成果對遠程監(jiān)控系統(tǒng)的完整性起到了補充作用,對其實踐應(yīng)用起到了推動作用。
[Abstract]:With the development of the times, people's demands on the quality of life are also increasing. People generally want to live in a safe, comfortable and harmonious environment. Ultra-high-definition video surveillance has become an issue of high attention. We hope that if we stay home, we will be able to learn the process of the event and get the high-definition video information from the video surveillance. In this context, The embedded platform of Samsung S5P6818 chip based on ARM cotex-A53 is developed in this paper. A remote wireless monitoring platform for UHD H.265 with a resolution of 3840 脳 2160P based on Android 5.1 is designed. The development status and trend of smart home and related monitoring system are discussed in detail in this paper. At the same time, the development environment and related evolution of Android system are briefly discussed, then the Binder IPC mechanism and Camera system architecture design are introduced in detail, and the mechanism of Binder IPC and the communication process of Binder IPC mechanism are analyzed in detail. The structure of Camera system chromatography, the application design and the design of Camera preview data stream are introduced in this paper. The corresponding Binder IPC mechanism in Android system environment and the basic framework of Camera subsystem are discussed systematically. In chapter 4th, the implementation of UHD resolution H.265 coding remote monitoring is described in detail, in which the design of UHD pixel camera driver and the overall design of camera Server and H.265 real-time bitstream transmission are emphatically studied. Through the debugging and installation of the system, the actual realization of the system is discussed, so that the programming of the HAL driver can be demonstrated in a complete and detailed way, and the matching parameters are obtained at the same time. Results and specific debugging operations. Through the installation and debugging of the system, it is verified that the data transmission and monitoring can be realized better under general conditions. The scheme solves the limitations of the original system, improves the stability and resolution of the system. To a certain extent, the shortcomings of the current remote monitoring system have been solved, and the ultra-high resolution H.265 remote monitoring function has been realized in this paper. The performance of the whole system is basically in line with the expected goal. The research results of this paper play a complementary role to the integrity of the remote monitoring system and promote its practical application.
