中文摘要：

通过对棉株形态拓扑结构特征及空间分布规律的分析,提出一种利用三次样条插值曲线对植物参数进行控制的虚拟植株形态可视化方法,基于此方法生成棉桃、叶片、分枝等器官几何模型,并按照器官位置参数以逐级寻迹的方式构建棉株群体,以MATLAB为开发工具,开发了基于形态参数的棉花可视化系统,进行动态碰撞检测与参数优化,实现了棉株群体可视化展示和三维位置点坐标数据的输出。

英文摘要：

According to the analysis of cotton morphological topology characteristics and spatial distribution law,a virtual plant visualization method was proposed using three spline interpolation curves to control the plant parameters. Based on this method,geometrical models of organs including bolls,leaf,branch,etc were generated to build cotton group under the organ position parameters with a tracing method step by step. The model could effectively reflect the distribution characteristics and spatial topological structure of cotton plant shape through comparative analysis. Finally,MATLAB was used as the developing tool to exploit a visualization system based on the cotton morphological parameters,then we conducted dynamic collision detection and parameter optimization,and achieved the output of cotton population visualization display and three-dimensional position coordinates data. Providing certain research value and application prospect of this research can be for agricultural research and teaching,crop growth design and management control field.
