| 摘 要： | 给出一种基于细分曲面技术实现散乱数据点的多分辨率曲面重构的方法。在曲面重构过程中,依据灰度图像边缘检测思想分析散乱数据特征值,将这些特征值生成纹理特征曲线进行曲面细分,从而形成了多分辨率网格模型结构。经过测试,该方法不仅重构曲面时间短,同时构造出的细分曲面能较好地反映原始数据的细节特征。

| Abstract: | A subdivision surfaces based method is provided for implementing the multi-resolution surface reconstruction from scattered data.In surface reconstruction process,the feature values of scattered data are analyzed using the idea of gray image edge detection.Subdivision surface is performed on texture feature curves which are generated from these feature values,so to have formed the multi-resolution mesh model structure.Tests indicate that this method reconstructs surface in short time and the subdivision sur... |
