基于自适应紧支撑径向基函数的点云三维建模

激光扫描仪(Laser'Scanner,LS)获得的点云数据由海量全离散的矢量坐标点构成.由于点云数据没有明显的形体信息和拓扑关系信息,考虑数据本身蕴含的丰富信息,采用改进后的自适应紧支撑径向基函数(AdaptiveCS-RBF)算法对点云数据进行曲面重建.在介绍紧支撑径向基函数数学模型的基础上,采用激光扫描获得同济大学孔子头像点云数据进行实例建模,通过比较不同建模参数获得的模型,分析该方法的应用效果.     

陡坡密集点云双重滤波方法研究

用地形三维激光扫描仪监测陡坡表面的细微变化,关键技术之一是对原始点云的精确滤波,即从密集点云中准确滤除非地形点,保留真实地形点。针对地势陡峭、表面复杂、植被多、密度分布极不均匀的陡坡点云,笔者发展了一种双重滤波方法:在对原始点云进行投影面变换的基础上,采用变窗口均值限差法滤除明显的非地形点,完成粗滤波;通过局部区域增长法找出绝大多数地形点,以占优势的地形点为参考,用局部最小二乘曲面拟合法对剩余未分类数据点进行检核,分离出非地形点,完成精滤波。文中选用3个不同类型的陡坡点云实例验证了该方法对于陡坡密集点云具有良好的滤波效果。该算法对野外大场景三维激光扫描点云滤波也有一定的参考价值。     

基于TLS技术的矿区地表沉降快速自动获取研究

为实现快速自动地从海量点云中获取地表沉降信息,该文提出了一种基于TLS技术的矿区沉降信息快速自动获取方法。对点云数据完成预处理后,首先以相同网格划分开采前后点云数据,然后利用改进的反距离权重法插值求取网格结点坐标,匹配相同网格结点作为同名点并求取下沉量,最后获取下沉曲线与下沉DEM,该方法实现了矿区地表形变的全面分析,能够快速自动地获取地表沉降信息。采用Riegl VZ-1000扫描仪采集某沉陷区开采前后点云数据,经过实验分析表明:该方法能够实现快速自动提取同名点、下沉点、下沉曲线与下沉DEM;将计算结果与实测值进行对比分析与精度分析,得到沉降结果符合实际地形变化情况,验证了该方法的可行性。该研究为三维激光扫描技术应用于地表沉降监测提供了支持。     

一种改进的基于法矢方向调整的平面点云分割方法

智慧城市的蓬勃发展和快速推广,使得三维建模成为当前热点研究方向。平面点云分割是三维点云建模中数据处理的关键环节。该文提出一种三角面片法向量方向调整方法,通过后续对邻近法向量进行加权平均估算实现平面点云的分割。首先采用八叉树的空间划分方法将无序的点云建立索引,利用K紧邻搜索获取参考点的K个邻近点,然后将该局部点构建不规则三角网并且得到包含参考点的所有三角面片以及三角面片的法向量,并通过将三维点投影到二维平面,利用平面三角形两边向量叉乘的方法,判断并调整各三角面片的顶点排列顺序,使三角面片的法向量一致化,最后对包含参考点的所有三角面片的法向量加权平均,估算参考点的法向量,根据点云法矢一致、共面的原则将平面点云分割出来。以徕卡Scanstation 2型扫描仪获取点云数据,对该方法进行检验,结果显示其能较好地实现对点云法矢量方向的调整与估算,并对平面点云数据进行分割提取。

文章提出一种完整的全自动化处理框架,基于三维激光点云数据对高速公路和城市道路场景的杆状目标进行了检测和分类,主要包括3个步骤：数据预处理、杆状目标检测和分类。其中,在数据预处理阶段,采用基于布料模拟滤波算法自动分离地面点和非地面点,然后基于欧氏距离聚类方法对非地面点进行快速聚类,以及采用迭代图割算法进一步分割目标对象;在目标检测阶段,集成先验信息、形状信息和位置导向搭建滤波器,对杆状目标进行检测;在对象分类过程中基于多属性特征,利用随机森林分类器对目标的特征进行计算和分类。并使用3个道路场景数据集进行测试,结果显示,3个数据集的整体MCC系数为95.6%,分类准确率为96.1%。这说明文章所构建方法具有较高性能。另外,该方法还可以鲁棒地检测杆状目标的重叠区域,较为适应复杂程度不同的道路场景。     

顾及矢量特征的机载LiDAR点云数据压缩方法

LiDAR技术可获取海量点云数据,数据压缩是点云数据预处理的一个重要环节。该文结合大范围城市区域高程范围随区域变化大的特点,提出一种有效的压缩策略。该策略主要通过建立高程方向不均等的三维格网来提高邻域点集的搜索效率,并根据某一压缩准则计算特征量对数据进行压缩。将该策略应用于上海浦东某区域,并与均匀采样法进行比较,证明其能有效提高点云数据压缩效率。     

基于动态椭圆的LiDAR数据窗户边界提取研究

针对复杂建筑物立面中窗户精细提取的难题,该文基于车载LiDAR数据提出一套完整的不规则窗户边界提取方法:先通过RANSAC算法探测建筑物主墙面点云,借助语义特征分离墙面和非墙面点云;再通过坐标变换,将非墙面点云转换到水平面,采用格网对水平面内点集的邻域关系进行判断,使用平面八邻域连通性探测方法对二维平面内窗户点进行聚类,分别存储聚类后的每一个窗户点云;然后采用改进的动态椭圆凸壳算法,检测聚类后各窗户边界轮廓点;最后对窗户点云坐标逆变换,得到建筑物立面中的窗户边界。通过实验验证了该算法的准确性。

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.
