Research on Recognizing Method of DMI Display Information Based on Image Process

本文为实现CTCS-3级列车控制车载设备人机界面(DMI)显示信息的自动识别功能,在完成静态图片处理算法研究之后,提出了一种结合Open CV库函数完成视频显示及数据保存的方案,从而实现了对DMI显示信息的自动识别。并通过实验验证了本方法自动识别的效果,以及对视频信息处理的时间性能指标。实验结果表明,本文所提出的方法能满足对DMI显示信息的自动识别需求,识别出的的信息可作为下一步研究DMI自动操作的参考依据,为实现CTCS-3级车载设备功能的自动测试奠定了基础。

In order to recognize CTCS-3 DMI display information automatically, an image process method is proposed. After studying on static image process algorithm, it proposes a scheme for DMI video process with OpenCV functions. Finally, experiments are made to check the method, and for video, time performance index of the algorithm is given. Experiments show that the method in this paper can meet the demand of DMI display information automatic recognition. The information extracted may be used as reference for the study of DMI automatic operation, it lays the foundation for the automatic test of CTCS3 onboard equipment
