高速公路视频分析计算平台性价比分析

Expressway Video Analysis and Calculation Platform Cost Performance Analysis

高速公路车速快,交通事件的影响大、破坏性强。因而,国内外高速公路管理部门一直十分重视交通事件的快速检测和处理,最大程度减少交通事件构成的破坏。其中,视频监控技术是一项应用非常有效的手段。目前,我国高速公路基本完成了视频监控的全覆盖,但是视频自动分析方法及其计算平台的选择和服务器部署在交通管理中的应用有待进一步改善。针对传统的视频分析系统存在的占用资源高、利用率低等特点,本文对视频分析中心的分析系统建设提出优化方案,并根据优化方案计算出该系统所需的计算能力,结合所需计算能力对工控机、GPU、服务器集群几种方案进行了性价比分析,给出了优化建议。

The speed of the expressway is high,and the impact of traffic events is large and destructive.Therefore,the expressway management departments at home and abroad have always attached great importance to the rapid detection and treatment of traffic incidents,minimizing the dam-age caused by traffic incidents.Among them,video surveillance technology is a very effective means of application.At present,China’s expressway has basically completed the full coverage of video surveillance,but the selection of video automatic analysis methods and their computing platforms and the application of server deployment in traffic management need to be further improved.In view of the high resource consumption and low utilization rate of the traditional video analysis system,this paper proposes an optimization scheme for the analysis of the Video analysis center’s analysis system,and calculates the computing power required by the system according to the optimization scheme.The cost performance analysis of several schemes of in-dustrial computer,GPU and server cluster was carried out,and the optimization suggestions were given.
