| 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 controlli... |
