摘　　要：以高精度免棱镜全站仪作为数据获取手段,在三次Bezier曲线最小二乘分段拟合圆柱管轴线的基础上,应用遗传优化算法求取空间线间的最短距离,从而求取节点中心坐标,并用MATLAB编程实现数据处理自动化和可视化。Taking the high-precision total station without mirror as means of data acquisition,the node center coordinates can be obtained based on computation of the shortest distance between lines with genetic optimization and cylindrical tube axis segment least square fitting with cubic Bezier cure.The automatic processing and visualization of data are done with MATLAB.
