摘　　要：为实现对植物根系的原位构型进行三维可视化和定量分析,针对根系分割区域数据导致可视化以及交互测量产生信息冗余等问题,提出一种基于改进骨架模型的植物根系三维构型可视化方法。通过建立根系稀疏云点骨架化模型,提出由原始切片分割数据对根系进行三维骨架化建模并可视化的方法。开发软件平台并通过实验验证了该方法可行性,模型对真实的原位根系具有理想的拟合效果,为根系构型参数的检测和定量分析提供了一种基础平台。To realize the 3D visualization and the quantitative analysis on plant roots system in situ, aiming at the problems that a mass of data points from the skeleton model lead to the information redundancy in visualization and interactive measurement, a new modeling method based on the 3dimension plant roots system＇ s skeleton model was proposed. A new way to convert a set of paralleling 2D slices original data into the visualized modeling by establishing a sparse cloud points model was proposed. The software system of the platform was developed and the simulation experiments provided an analysis of algorithmic availability. This model performs well at approximating the realistic roots in the simulation, and it is of great importance to the visualization and quantitative analysis in the root system.
