摘要
针对接触网几何参数高速、动态测量的实际需要,提出一种利用改进的Harris角点检测算法对接触网的几何参数进行提取,并计算提取图像中的角点的曲率及梯度.在分析检测结果与接触网几何参数检测的特殊性后,绘制出导高变化曲线和动态拉出值曲线.利用导高的变化曲线对受流参数硬点进行分析.结果表明,该方法可以成功对该段线路内接触网的受流参数硬点进行判别.
Aiming at dynamic high-speed of catenary detection, an improved Harris corner detection algorithm are used to extract the catenary geometry parameters, and the curvature and gradient of extractive picture are calculated. After analysing the detective result and the particularity of catenary geometry parameters, the curve of height of conductor and dynamic stagger value are obtained to analyze hard point of current collective parameters. The result shows that the method can successfully judge this road section hard point of current collective parameters.
