摘　　要：采用全站仪自由设站获取轨道测点的坐标数据,使用Matlab软件拟合最小二乘法圆,得到拟合圆半径与圆心坐标,然后进行偏差计算,最后将偏差值与起重机轨道跨度标准进行对比即可判定轨道的圆度是否合格。The total station is used to set the station freely to obtain the coordinates of rail measuring points, and Matlab software is used to fit the least square circle to get the fitting circle radius and center coordinates. The deviation calcula- tion is performed. Comparing the deviation value with the crane runway span standard can verify whether the rail roundness is qualified.
