[目的]研究幼苗期油菜的几何造型。[方法]通过对幼苗期油菜的形态结构和生长过程的观测分析,提出了基于形态结构特征参数的幼苗期油菜三维形态数学模型及其可视化方法。根据油菜各器官的形态结构特征提取了不同的控制参数,并利用3次B啨zier曲面生成大小各异的油菜叶片与叶柄模型,同时采用上下底面积不同的圆柱体作为主茎模型,最后通过旋转、缩放、拼接等操作实现了幼苗期整株油菜的三维重建。[结果]该方法具有一定的可控性,简单方便,可快速构建幼苗期油菜几何模型。[结论]为油菜形态模型研究提供了参考。

[Objective] The paper was to study the geometric modeling of rape（Brassica napus L.） during seedling stage.[Method] Based on the analysis and observation of morphological structure and growth process of rape during seedling stage,a characteristic parameters-based three-dimensional mathematical model of rape and its visible method was proposed.The individual control parameters were extracted according to the morphological structures of various organs of rape.Different sizes of leaf and petiole model were constructed by using cubic Bézier surface.The cylinder with different upper and lower bottom area was adopted as the main stem model.Finally,three-dimensional reconstruction of whole Rape plant during seedling stage was achieved through the operations of rotation,scaling and splicing.[Result] This method had certain controllability,which was also easy and convenient,and could quickly use to build the geometric model of rape during seedling stage.[Conclusion] The results provided reference for study on structural model of rape.
