| 摘 要： | 为了实现对电力接触导线几何参数的实时、有效检测,从而保证电气化铁路安全运营,延长导线使用寿命,提出了基于图像处理的非接触测量方案.根据双目立体视觉技术的测量原理,推导了电力接触导线几何参数测量的数学模型.对图像处理算法进行了深入研究,采用了基于零交叉点算法与二次曲线拟合相结合的亚像素边缘检测方法,提取导线磨损创面的边界点坐标值,实现了导线高度、拉出值和磨损面宽度等几何参数的测量.通过大量实验进行了原理验证,实验结果表明文中提出的方案思路正确、可行,为电力接触导线几何参数测量系统的研制打下了良好的基础.

| Abstract: | In order to prolong the use longevity and guarantee the safety of the electrified railway,the geometry parameters of electric contact wire must to be measured real-time and effectively.This paper presented a non-contact detecting method based on image process.Expressions of the geometry parameter of electric contact wire were gained according to the theory of the binocular stereovision technique.An approach was presented to detected image edge at the level of sub pixel using LOG function and conic fitting w... |
