【摘要】：隨著中國(guó)車輛日益猛增,為了提高車輛的出行安全,對(duì)車輛進(jìn)行監(jiān)控的需求越來越大。為了以后的調(diào)查取證視頻需要持久化保存,分布式云存儲(chǔ)技術(shù)為解決海量視頻文件的存儲(chǔ)提供了完美的解決方案。 本文分析了車載視頻監(jiān)控系統(tǒng)的功能需求,接著從設(shè)計(jì)的角度給出了該系統(tǒng)的功能模塊的劃分,并重點(diǎn)分析了分布式數(shù)據(jù)庫(kù)模塊的具體需求和設(shè)計(jì)。該系統(tǒng)將記錄的車載監(jiān)控的視頻按時(shí)間片劃分為視頻文件存儲(chǔ)在HDFS中,同時(shí)將視頻文件在HDFS中的路徑和其他視頻相關(guān)信息記錄在HBase中。本文重點(diǎn)設(shè)計(jì)和分布式云存儲(chǔ)模塊的類SQL復(fù)雜查詢功能,通過使用Expression模擬SQL語(yǔ)句中的功能,然后使用ExpressionFilter和GroupBy實(shí)現(xiàn)了類SQL語(yǔ)句的查詢。然后根據(jù)設(shè)計(jì)給出了各模塊的實(shí)現(xiàn)代碼。 本文設(shè)計(jì)實(shí)現(xiàn)的車載視頻監(jiān)控系統(tǒng),具有技術(shù)先進(jìn)、性能良好、成本低廉的特點(diǎn),滿足了廣大用戶對(duì)視頻監(jiān)控實(shí)時(shí)性的要求,同時(shí)滿足了用戶對(duì)海量視頻文件的存儲(chǔ)、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.
