稀疏点云的曲面重构

为研究曲面重构中的一类特殊数据,针对稀疏点云提出了一种高效、简单、实用的曲面重构方法。首先分析稀疏点云自身特点,按特征进行预处理与分块。然后依次拟合曲线,通过参数化优化与调整,得到适合造型的曲线,并且引入迭代、渐进的思想来弥补部分数据的缺失。最后利用两种典型重构方法分别对不同分块数据进行曲面重构。实例表明,该方法解决了稀疏点云的曲面重构过程中由于点云信息量少造成的重构困难。

The Surface Reconstruction for Few and Scattered Points Cloud

In order to deal with a kind of special data such as few and scattered points cloud in the reconstruction of surface model,it analyzes the feature of the data itself,realizes the pre-processing and segmentation according to the data feature.After parameterization and optimization of the section curves,it builds the reconstruction model of the result curves surface with two typical methods.The example shows that the reconstruct surface model of few and scattered points cloud is efficient,simple,practicable.
