A steel rail profile dynamic detection error correction method based on actual measurement position positioning realizes actual measurement position positioning by using labels and utilizing characteristics of a steel rail profile dynamic measurement system, and greatly reduces an actual measurement profile position range through a label arrangement method associated with sampling intervals; the overall error correction of the system is realized through the weighted average of the profile correction parameters after the actual measurement profile is accurately positioned.
一种基于实测位置定位的钢轨廓形动态检测误差修正方法,使用标签并利用钢轨廓形动态测量系统的特性,实现实测位置的定位,通过关联采样间隔的标签布置方法,大幅缩小实测廓形位置范围;通过实测廓形精确定位后廓形修正参数的加权平均,实现系统整体的误差修正。
