| With the rapid development of public transport system, the higher request is put forward to the video monitoring system. At the same time, the development of the Linux system, Web technology and distributed technology provides the technical support for vehicle video monitoring system. According to the practical reqirements of vehicle mobile video monitoring system combined with open source distributed HDFS framework, a new vehicle video monitoring system with two architecture of B/S and C/S is designed and realized based on the Linux platform. This system aims at solving the problems existing in the current video monitoring system, such as limited storage of streaming media server, poor scalability and the singleness of operation platform.In this thesis, research the application status of vehicle video monitoring system and the latest relevant technology, combined with the vehicle video monitoring system of the new requirements, propose a new design scheme of video monitoring system based on Linux. Introduced the technologyof Web and distributed storage, choose the appropriate technical solution. To meet the actual requirements of vehicle video monitoring system, using the software modular design the overall scheme of vehicle video monitoring system and each module. Application of Live555 and FFmpeg in the development of video transmission and video storage module, the application of HDFS distributed file system as storage unit, video monitoring client is developed by using Libvlc and Qt graphics interface library.Based on Linux platform, using C++ as the main development language, using the above open source library, vehicle video monitoring system of C/S architecture is implemented. And using the Apache+PHP+MySQL scheme of video monitoring system B/S architecture implementation under Linux.At the end, the video monitoring system based on Linux is tested, the results show that the system can meet the actual requirements of vehicle video monitoring. |
