    摘要:

    三维激光扫描点云中的平面特征提取是3D建模的重要组成部分,是一个重要的研究领域。在建筑物平面提取的过程中,针对传统的单点式区域生长方法在生长时会使拟合得到的平面与真实点云平面存在偏差,导致面块间的粘连的问题,本文提出了一种逐条线区域生长方法,考虑到建筑物的平面都具有规则的形状,而平面是由一条条直线组成的,因此在生长的过程中加入了平面的形状这个先验条件。实验结果表明,该方法能够消除面块间的粘连,有效改善平面提取的精度。

    Abstract:

    The plane feature extraction of 3D laser scanning is an important component for 3D modeling,which also is a significant field of research.In the building plane extraction process,against traditional point-by-point region growing will make the fitting plane and real point cloud plane deviation,lead to the adhesions between the surface of the block,this paper presents a detailed lines region growing method,considering the building plane has a regular shape,and the plane ba straight line, so in the growth process of joined the flat shape the a prior conditions.The experimental results shows that this method can eliminate the adhesion between the surface of the block, and effectively improve the accuracy of the plane extraction.
