摘要

面对移动测量系统海量的数据,人工获取交通标志类型效率低下,本文提出基于移动测量系统的交通标志自动提取解决方案.首先,分析了移动测量系统交通标志图像的特点,在此基础上提出了合适的交通标志自动检测和识别的方法；然后,设计了交通标志自动提取流程；最后,以上述理论为基础设计实现交通标志自动提取模块,包括自动提取模块的数据库设计和功能设计,系统实验表明该系统可以大大提高交通标志提取的效率,降低作业成本.%Faced with the vast amounts of data of the mobile mapping system,manual access to the type of traffic signs is so inefficient.In this paper we propose a solution to automatic extraction of traffic signs based on mobile mapping system.Firstly we analyze the characteristics of traffic signs from mobile mapping system,then appropriate automatic detection and recognition methods are proposed,then we give a detailed flow of automatic extraction of traffic signs.Finally based on the above theory,we design and realize automatic extraction modules of traffic signs including automatic extraction module database design and functional design,and system experiments show that the system can greatly improve the efficiency of the extraction of traffic signs and reduce costs.
