摘要
【目的】实现烟草的数字化与可视化。【方法】本文采用模板技术对烟草植株进行三维重构,首先通过三维数字化仪对烟草器官进行测量和形态特征提取,然后基于形态结构特征分别建立了烟草叶片、花朵、果实和茎节等器官的参数化几何模型,保存为模板文件,最后调用相应的模板文件,结合图形变换方法拼接成完整植株几何模型。【结果】利用本文方法可方便构造烟草各主要时期的三维模型。【结论】所建立的烟草植株几何模型具有较高的真实感,为其三维形态交互设计和可视化模拟提供了技术支撑。
[Objective] The objective of this study is to realize the digitization and visualization of tobacco, [Method] In this paper, the template technique was used for three-dimensional reconstruction of the tobacco plant and visualization, The measured data of tobacco organic were firstly obtained using 3D digital instrument and image processing; then the simulation for tobacco leaves, flowers, fruit and stems were realized accordingly to different parametric descriptions based on morphological characteristics, and saved them as template files. At last, the complete model was constructed with graphical transformation operations on them, [Result] Using this method can facilitate the construction of the major periods of tobacco with 3D model. [Conclusion] The result shows that the tobacco model rebuilt by this method has more reality, which offers a technique support for its iteraetion design and visualized simulation,
