摘　　要：利用三维激光扫描仪对建筑物墙体进行整体扫描,在Huber选权迭代法中引入RANSAC算法思想,借此对墙体的点云数据进行筛选性最小二乘拟合,结合MATLAB软件模拟墙面,计算得到墙面平整度,提高墙面拟合精度,减小粗差的影响。Scanning on the wall of a building by using a 3D laser scanner,the RANSAC algorithm was added to the Huber weight iteration method,then we take on the wall of the point cloud data filtering of least squares fitting simulation wall.This paper combined with MATLAB software,calculated surface flatness,improved the precision and reduced the influence of outliers.
