基于图像处理的接触网动态几何参数测量研究

为了保证高速列车安全运行,需要对接触网的高度以及拉出值等几何参数进行经常性的检测。接触式检测在高速铁路试验中会增大试验数据与实际运行数据之间的差异,从而导致接触网测试参数误差变大。现利用车顶摄像机测量接触网几何参数进行可行性分析,提出了一种利用图像处理技术,对摄像机影像进行处理,提取并计算接触网动态高度以及拉出值等参数的方法。试验结果表明系统具有设备安装简单,测量精度高等特点,具有充分的可行性。

Study on OCS Dynamic Geometric Parameters Detection Based on Image Processing

In order to assure that the high-speed train can operate normally,it is necessary to ensure the security of catenary and detect catenary geometry parameters frequently.Traditional detection methods will reduce the similarity between detection pantograph and actual pantograph,which results in the error of catenary detection parameters.In this paper,the feasibility of detecting catenary dynamic geometric parameters using roof camera is analyzed.An image processing based non-contact detection method that calculates and detects contact line height and dynamic pull-out value is proposed.The experimental results show that the system is feasible,and has the characteristics of simple installation and high precision.
