基于逆向工程技术的鼹鼠前爪趾甲几何模型

Geometrical Model of Nail of the Mole's Manus Using Reverse Engineering Method

利用三维激光扫描系统对鼹鼠前爪趾甲的表面进行扫描,获得趾甲腹面和背面的表面数据点云,对扫描数据精简、平滑处理后,采用点—线—面方法进行了曲面重构,最后进行了重构曲面模型精度分析。分析表明,鼹鼠前爪趾甲重构曲面模型满足精度条件,为后续的几何形态定量分析提供了模型基础。

The data clouds of ventral and dorsal surface of the nail for the mole＇s manus were obtained with 3 - D laser scanning system. The surface reconstruction was made using the point - line - surface method after they were reduced and made the smoothing processing. Moreover, the model precision of surface reconstruction was analyzed. The results showed that the precision was satisfactory and the surface reconstruction can be used for the quantitative analysis of geometric shape for the mole＇s nail.
