The invention discloses a track gauge detection method and device for a railway turnout. The method comprises the steps that turnout section point cloud data and pre-established turnout template data are acquired; matching the turnout section point cloud data with pre-established turnout template data, and determining a to-be-detected region of the steel rail; determining position information of a rail top according to the to-be-detected region of the steel rail; determining the position information of the gauge point according to the preset position relation between the rail top and the gauge point and the position information of the rail top; and determining a gauge detection result according to the position information of the gauge points. According to the invention, the point cloud data of the turnout section is matched with the pre-established turnout template data, and the gauge detection result is determined according to the position information of the gauge point, so that the accuracy and efficiency of gauge detection of the railway turnout are improved.

    本发明公开了铁路道岔的轨距检测方法及装置,方法包括:获取道岔截面点云数据及预先建立的道岔模板数据;将道岔截面点云数据与预先建立的道岔模板数据进行匹配,确定钢轨待检测区域;根据钢轨待检测区域确定轨顶的位置信息;根据预设的轨顶与轨距点的位置关系,及轨顶的位置信息确定轨距点的位置信息;根据轨距点的位置信息确定轨距检测结果。本发明将道岔截面点云数据与预先建立的道岔模板数据进行匹配,根据轨距点的位置信息确定轨距检测结果,提高了铁路道岔的轨距检测的准确性及效率。
