摘要：

为了对生菜进行快速三维重构，本文将逆向工程的思想引入到生菜几何建模中来，提出了一种基于参数模板的生菜几何建模方法。借助三维扫描设备构造具有多分辨率的生菜器官模板，分析生菜植株形态结构特征，提取特征参数，进而通过形态参数对模板进行控制，并最终组装成为参数化的生菜几何模型。实验结果表明，该方法可以快速、便捷地重构出具有较高真实感的生菜几何模型，对曲面难以构造的植物器官及植株几何建模具有一定的参考意义。

Abstract:

In order to reconstruct the three-dimensional model of lettuce rapidly, the idea of reverse engineering was introduced to the lettuce geometric modeling and a template based on parameters method is proposed. Firstly, with the help of three-dimensional scanning device, multi-resolution lettuce organ template was constructed. Then, the morphological characteristics of lettuce plants were analyzed to extract characteristic parameters. Finally, parametric geometric model of lettuce plant was assembled through controlling the morphological parametric and the templates. The results showed that this method could reconstruct high realistic geometric model of lettuce quickly and easily, and have reference value for complicated structure plants.
