The invention discloses a third rail position detection method and system, and the method comprises the steps: respectively collecting the contour data of a third rail, the contour data of a first steel rail, and the contour data of a second steel rail, the contour data of the first steel rail comprises two contour scanning data located below the rail surface of the first steel rail; the first steel rail is close to the third rail; determining a track plane based on the contour data of the first steel rail and the contour data of the second steel rail; determining a central point of the third rail based on the contour data of the third rail; calculating a guide height value of the third rail based on the rail plane and the center point of the third rail; and calculating the pull-out value of the third rail based on the contour data of the first steel rail, the central point of the third rail and the rail plane. According to the invention, the accuracy of third rail position measurement can be improved.
本发明公开一种第三轨位置检测方法及系统,包括分别采集第三轨的轮廓数据、第一钢轨的轮廓数据和第二钢轨的轮廓数据,所述第一钢轨的轮廓数据包括位于所述第一钢轨轨面下方的两个轮廓扫描数据,且所述第一钢轨靠近所述第三轨;基于所述第一钢轨的轮廓数据和所述第二钢轨的轮廓数据,确定轨道平面;基于所述第三轨的轮廓数据,确定所述第三轨的中心点;基于所述轨道平面和所述第三轨的中心点,计算所述第三轨的导高值;基于所述第一钢轨的轮廓数据、所述第三轨的中心点以及所述轨道平面,计算所述第三轨的拉出值。本发明可提高第三轨位置测量的准确度。
