一、引言随着我国高铁事业的不断发展,铁路已成为人们最普遍的出行方式之一。与此同时,铁路的检测维修也变得日益重要,特别是对于中铁、中建及宝钢等客户,精确检测出铁路钢轨的变形是其日常检测的基本工作。传统方法是采用全站仪测量钢轨的边线,但因为全站仪只能测量单点,对于同一钢轨,测量点位置的不同,所得结果也有差异,全站仪测量并不能完全反映出钢轨的所有尺寸信息。随着三维激光扫描技术的发展,三维激光扫描仪在钢轨尺寸检测中的应用
I. INTRODUCTION Along with the continuous development of high-speed railway in our country, the railway has become one of the most popular mode of travel. At the same time, testing and maintenance of the railway has also become increasingly important. Especially for the customers such as China Railway Construction Corporation, China Construction Bank and Baosteel, the accurate detection of the deformation of the railroad track is the basic routine inspection. The traditional method is to use the total station to measure the rail edge, but because the total station can only measure a single point, for the same rail, the location of the measurement point is different, the results are also different, total station measurement does not fully reflect the rail all Size Information. With the development of 3D laser scanning technology, the application of 3D laser scanner in the detection of rail size
