【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。
[Abstract]:Aiming at the problem of 3D laser scanning technology in making ontology map of ancient cultural relic, according to the basic idea of point cloud data, a new method of making ontology map of ancient cultural relic based on 3D model is put forward. The feature information is extracted from 3D model and point cloud data by the principle of uniform distribution, and the feature information is well preserved, and the raster image is matched with the feature vector based on point cloud data and 3D model by affine transformation. Make ancient cultural relics body map. The results show that the matching accuracy of the method based on point cloud is slightly higher than that of the method based on 3D model, but both of them can reach cm level. The method of making ontology map based on 3D model is intuitionistic and the error transfer in the process of making is less than that of the former. It is a method of making ontology map of ancient cultural relic which can keep the precision better on the premise of rapidity. It expands and enriches the application of mapping technology of ancient cultural relic ontology map.
