【摘要】：随着时代发展,人们对生活质量的要求也在不断提高。人们普遍希望生活在安全、舒适、和谐的环境中,由此,超高清视频监控成为目前关注度较高的研究问题。大家希望足不出户,便能从视频监控中得知事情的过程,获知高清摄像信息。在此背景下,本文开发了以ARM cotex-A53的三星S5P6818芯片的嵌入平台为核心,设计基于Android 5.1的分辨率达3840×2160P的UHD H.265超高清高性能远程无线监控平台。论文深入探讨了智能家居以及有关的监控体系的发展状况及趋势,同时针对Android系统的开发环境和相关演变问题进行简要的论述,然后详细介绍了Binder IPC机制以及Camera系统架构设计,具体分析了Binder IPC的机制情况以及Binder IPC机制通信过程,全方位介绍了Camera的系统层析结构、应用设计以及Camera预览数据流的设计,针对Android系统环境之中对应的Binder IPC机制和有关的Camera子系统的基础框架开展系统的论述,为后文的有关分析进行良好的铺垫。第四章详尽说明了UHD分辨率H.265编码远程监控的实现,其中重点研究了UHD像素摄像头驱动设计、Camera Server总体设计和H.265实时码流传输的设计,通过对系统的调试与安装,探讨该系统的实际达成,从而使得针对HAL驱动的编制得到完整细致的论证,同时得出了配套的参数、结果和具体的调试操作。通过系统的安装与调试,验证了一般条件下能较好地实现数据的传输监控。该方案解决了原有系统的局限性,提高了系统的稳定性、分辨率,在一定程度上解决了目前远程监控系统存在的不足。论文实现了超高清分辨率H.265远程监控功能,整个系统性能基本符合预期目标。论文的研究成果对远程监控系统的完整性起到了补充作用,对其实践应用起到了推动作用。
[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.
