基于点云数据的地籍测量信息提取方法

Cadastral survey information extraction method based on point cloud data

目前传统的数字化地籍测量信息提取方法通过对地籍信息进行编码,实现对地籍信息的提取。由于缺乏对主要特征数据的提取,导致提取效率较低。对此,文章提出基于点云数据的地籍测量信息提取方法。利用三维扫描仪扫描地籍信息,获取点云数据,提取出双阈值点云特征数据。对点云数据进行降噪拼接处理,得到完整的地籍测量信息。在实验中,对构建出的地籍测量信息提取方法进行了提取效率的验证。经实验分析证明,利用提出的地籍测量信息提取方法对不同地籍模型进行信息提取,其耗费的提取时间较短,具备较高的提取效率。

At present,the traditional digital cadastral survey information extraction method realizes the extraction of cadastral information by encoding cadastral information.Due to the lack of extraction of main feature data,the extraction efficiency is low.Therefore,this article proposes a cadastral survey information extraction method based on point cloud data.By scanning cadastral information with 3D scanner,point cloud data was obtained,and double threshold point cloud feature data was extracted.The complete cadastral survey information is obtained by noise reduction and concatenation of point cloud data.In the experiment,the extraction efficiency of the constructed cadastral measurement information extraction method was verified.The experimental analysis proved that the proposed cadastral measurement information extraction method was used to extract the information of different cadastral models,and the extraction time was shorter and the extraction efficiency was higher.
