【摘要】：随着中国车辆日益猛增,为了提高车辆的出行安全,对车辆进行监控的需求越来越大。为了以后的调查取证视频需要持久化保存,分布式云存储技术为解决海量视频文件的存储提供了完美的解决方案。本文分析了车载视频监控系统的功能需求,接着从设计的角度给出了该系统的功能模块的划分,并重点分析了分布式数据库模块的具体需求和设计。该系统将记录的车载监控的视频按时间片划分为视频文件存储在HDFS中,同时将视频文件在HDFS中的路径和其他视频相关信息记录在HBase中。本文重点设计和分布式云存储模块的类SQL复杂查询功能,通过使用Expression模拟SQL语句中的功能,然后使用ExpressionFilter和GroupBy实现了类SQL语句的查询。然后根据设计给出了各模块的实现代码。本文设计实现的车载视频监控系统,具有技术先进、性能良好、成本低廉的特点,满足了广大用户对视频监控实时性的要求,同时满足了用户对海量视频文件的存储、快速的查找和易于管理的要求。
[Abstract]:With the increasing increase of vehicles in China, there is a growing demand for vehicle monitoring in order to improve the safety of vehicles. The distributed cloud storage technology provides a perfect solution for the storage of large amount of video files. This paper analyzes the functional requirements of the vehicle video surveillance system, and then from the design point of view, the functional modules of the system are divided, and the specific requirements and design of the distributed database module are analyzed. In this system, the recorded on-board surveillance video is divided into video files according to time slice and stored in HDFS, while the path of video files in HDFS and other video related information are recorded in HBase. This paper focuses on the design and distributed cloud storage module SQL like complex query function, through the use of expression simulation of SQL statements, and then use expression filter and GroupBy to realize the SQL statements query. Then the implementation code of each module is given according to the design. The vehicle video surveillance system designed and implemented in this paper has the characteristics of advanced technology, good performance and low cost. It can meet the real-time requirements of the majority of users and the storage of mass video files. Fast lookup and easy-to-manage requirements.
