钢轨直线度是钢轨大型构件质量的重要指标，对钢轨厂的产品质量检测具有重要意义。目前钢轨厂直线度的测量仍然依靠人工使用直线度尺进行测量，导致测量速度慢、精度低。为此，提出了一种基于外边界支撑点模型的非接触测量方法。利用激光轮廓仪测量钢轨直线度原始曲线，采用本文提出的直线度曲线处理算法，得到中值滤波曲线，计算最大差值。结果表明，该方法具有良好的性能，并表明提出了一个更好的直线度测量方法比传统的手动测量使用物理直线度尺。
Rail straightness is an important index of the quality of large components of steel rails, and is of great significance for product quality testing in rail plants. At present, the measurement of straightness in rail factories still depends on the manual use of straightness rulers for measurement, which leads to low measurement speeds and precision. Therefore, we propose a non-contact measurement method based on the outer boundary support point model. Using laser profilers to measure the original curve of the rail straightness, the proposed straightness curve processing algorithm in this paper is used to obtain the median filter curve and calculate the maximum difference values. Results show excellent performance and indicate that the proposed method presents a better straightness measurement approach than traditional manual measurements using physical straightness rulers.
