三维测绘数据的减余转换与共享发布

本文提出一种适合三维测绘数据的共享转换与发布的基本流程:数据采集,预处理,初建模,格式转化,再加工,发布。其中原始数据的预处理是重要的一步,作者对重复点,零长度线,零面积面进行了简单删除操作,从而有利于简化数据方便后续处理与展示。最后作者利用共享数据结构对各种通用数据格式进行转换发布,并对各种格式作了简要分析与比较。

Reducing Redundancy Conversion of 3D Mapping Data for Sharing and Distribution

This paper provides a kind of method to share, convert and distribute 3D mapping data, which includes data collection, pre-process, pre-modeling, file format conversion, reprocessing and distribution. The pre-process is an important step of the whole process. The duplicate points, non-length edges, and non-area faces are deleted to reduce the redundant data in order to let later work easier to do and make the data suitable for 3D showing. The distribution and sharing for 3D mapping data should use the general engineer format, on the basis of the auto-collection using software to do further edition will finish a high quality and high effective digit production. So at last the data are distributed in 5 data file formats by the sharing data structure.
