The invention provides a railway turnout frog full-section profile measurement method, and belongs to the technical field of railway turnout frog measurement. In order to solve the problem that efficiency, convenience and precision are difficult to consider in railway turnout frog measurement, the invention provides a railway turnout frog full-section profile measurement method which comprises the following steps: sequentially acquiring a first image, a second image and a third image along the transverse direction of a turnout frog through a steel rail profile measurement instrument, the first image is a first wing rail profile, the second image is a point rail profile, and the third image is a second wing rail profile; splicing the first image, the second image and the third image according to the image overlapping position to obtain a full-section profile graph; and measuring the full-section profile of the turnout frog according to the full-section profile graph. The turnout frog full-section profile graph is formed by splicing the three images, the requirement for the working range of the steel rail profile measuring instrument is lowered, and therefore the size of the measuring instrument can be reduced, and the measuring efficiency, convenience and precision are considered.
本申请提供了铁路道岔辙叉全断面廓形测量方法,属于铁路道岔辙叉测量技术领域。针对铁路道岔辙叉测量难以兼顾效率、便捷以及精度的问题,本申请提供了铁路道岔辙叉全断面廓形测量方法,包括通过钢轨廓形测量仪沿道岔辙叉的横向依次获取第一图像、第二图像和第三图像,且相邻图像部分重合,第一图像为第一翼轨廓形图,第二图像为心轨廓形图,第三图像为第二翼轨廓形图;根据图像重合位置拼接第一图像、第二图像和第三图像,获得全断面廓形图;根据全断面廓形图测量道岔辙叉全断面廓形。本申请通过三张图像拼接形成道岔辙叉全断面廓形图,降低了钢轨廓形测量仪的工作范围要求,从而可减小测量仪体积,进而兼顾测量效率、便捷以及精度。
