城市轨道车辆综合线路图处理系统设计与开发

Design and development of urban rail vehicle integrated route map processing system

在城市轨道交通中,城市轨道车辆综合线路图的数据采集工作愈发重要,因图片不清晰导致识别准确率不高的问题时有发生。针对这种情况,设计了一种基于数字图像处理的城市轨道车辆综合线路图处理系统,通过运用MATLAB软件中图像处理工具箱和人机交互界面两种功能,实现了对城市轨道车辆综合线路图的快速处理,为后续城市轨道车辆综合线路图数据采集和智能识别建立了良好的基础。实验结果表明,通过该系统对一张综合线路图进行数据采集比现有方法准确率平均提高约25%,节约时间约30 min。

In urban rail transit,the data collection of urban rail vehicle integrated circuit maps is becoming more and more important,and the problem of low recognition accuracy due to unclear pictures often occurs.Aiming at this situation,an integrated circuit diagram processing system for urban rail vehicles based on digital image processing is designed.By using the functions of image processing toolbox and human-computer interaction interface in MATLAB software,the comprehensive road map of urban rail vehicles is realized.The rapid processing has established a good foundation for the subsequent data collection and intelligent identification of urban rail vehicle integrated circuit diagrams.The experimental results show that the data acquisition of a comprehensive circuit diagram by the system is about 25%higher than the accuracy of the existing method,and the saving time is about 30 min.
