中文摘要：

针对三维激光扫描技术在古文物本体图制作中的问题,根据点云数据进行本体图的基本思想,提出了一种新的基于三维模型的古文物本体图制作方法。采用均匀分布原则对三维模型与点云数据进行特征信息提取,较好地保留了特征信息;并利用仿射变换将栅格影像分别与基于点云数据与三维模型的特征矢量进行匹配,制作古文物本体图。分析对比数据表明,基于点云的方法匹配精度较基于三维模型的方法稍高,但两者精度均能达到cm级。基于三维模型的本体图制作方法操作直观且制作过程中的误差传递较前者小,是一种在快速的前提下仍能较好保持精度的古文物本体图制作方法,拓展并丰富了有关古文物本体图测绘技术的应用。

英文摘要：

Aiming at the problem of drawing ancient plank road ontology graphic based on 3Dlaser scanning technology,in view of the foundational idea of point cloud data mapping,a 3D model based method of ontology graphic drawing is proposed.Use the uniform principles to extract feature information of point cloud data and 3D model,and utilize them to match raster image based on the affine transformation theory to mapping ontology graphics.Compared the two method,the result shows that the accuracy of point cloud data based is little higher than that based on 3D model,but the latter has a more intuitive view than the former one when manipulate,it is a method that can guarantee both speed and accuracy to draw ontology graphic,and expended the application of antiquities ontology graphics of serving and mapping technology.
