逆向造型技术在动物标本三维建模中的应用研究

Research on the Application of Reverse Modeling Technique in Three-Dimension Modeling of Animal Specimens

基于逆向工程技术对三维实体模型重构的方法,以动物标本模型为例进行表面扫描的数字化处理,获得了实体的表征数据。通过对缺陷的几何修正,达到三维模型优化与重构的目的,从而实现了实体→数据→三维模型重构的过程。这种逆向建模技术的应用大大缩短了数字化几何模型的建立周期,降低了动物标本制作的难度,具有重要的实践意义。

Based on themethod of reverse engineering technique to reconstruct three-dimensional solid model, with the example of an animal specimen model processed by the digital surface scanning, the characterization data of the entity is obtained. Through the geometric correction of defects, three-dimensional model can be optimized and reconstructed toimplementing the process of the entity to the data, and to the three-dimensional model reconstruction. The period of establishing digital geometric model is greatly shortened by the application of this reverse modeling technology which also reduce the difficulty of making animal specimens at the same time, which is of great significance in practice.
