三维激光成像系统的点云模型真彩色处理方法

三维激光成像系统获得的点云数据精度高并且保有高精度的高程信息,然而特征信息不明显,没有保留全部的点和点的拓扑关系,无法直接判读地面物体;影像数据空间分辨率和精度低,并且缺少高程信息,然而其影像的特征连续,光谱信息丰富.因此,进行点云数据与影像数据融合方法的研究是目前三维激光成像系统研制的前沿性课题.针对点云数据与影像数据融合方法的研究,提出了一种三维激光成像系统点云模型真彩色处理的方法.实验结果显示,采用所提出的方法,不仅能够获得被扫描物体的位置信息和大小信息,而且能够得到被扫描物体的表面纹理细节信息.

A Method of True Color Processing of the Pointcloud Models of the 3D Laser Imaging System

The 3D laser imaging system can get high accuracy pointcloud data and keep the accurate elevation information. However, the feature information is not obvious, does not remain the topological relations among all the points, can not directly interpreter the ground object; The Spatial resolution and the accuracy of the image features and rich spectral information. Therefore, the research of the fusion method of the pointcloud data and the image data is a cutting-edge topic in the area of 3D laser imaging system. In allusion to the research of the fusion method of pointcloud data and image data, a method of true color processing of the pointcloud models of the 3D laser imaging system is presented. The experiment result shows that with the proposed method, it can not only obtain the position information and size information if the scanned object, but also the surface texture information of the scanned object.
