摘　　要：为了实现曲面建筑平立剖面图的精准测绘,将3D激光扫描技术应用到曲面建筑平立剖面图测绘工作中,实现测绘方法的优化。应用3D激光扫描技术获取曲面建筑点云数据,通过融合、去噪与过滤等步骤,实现对初始点云数据的预处理。提取曲面建筑轮廓线,经过曲面建筑结构数据测量和曲面建筑平立剖面图绘制两个步骤,输出曲面建筑平立剖面图的测绘结果。通过应用效果测试实验得出结论:通过3D激光扫描技术的应用,曲面建筑几何参数的测量误差明显降低,绘制的平立剖面图与实际曲面建筑结构之间的相似度更高,即3D激光扫描技术在曲面建筑平立剖面图测绘中具有良好的应用价值。In order to achieve accurate surveying and mapping of curved building plans and sections,3D laser scanning technology is applied to the surveying and mapping work of curved building plans and sections,achieving optimization of surveying and mapping methods.Apply 3D laser scanning technology to obtain curved building point cloud data,and preprocess the initial point cloud data through steps such as fusion,denoising,and filtering.Extract the contour lines of curved buildings,and through two steps:measuring the structural data of curved buildings and drawing the horizontal and vertical sections of curved buildings,output the surveying results of the horizontal and vertical sections of curved buildings.Through the application effect testing experiment,it is concluded that the measurement error of geometric parameters of curved buildings is significantly reduced through the application of 3D laser scanning technology,and the similarity between the drawn horizontal and vertical profiles and the actual curved building structure is higher.Therefore,3D laser scanning technology has good application value in the surveying and mapping of horizontal and vertical profiles of curved buildings.
