基于实测数据的小麦叶片模拟模型与三维重建--以偃展4110为例

摘要

Using specific wheat variety Yanzhan 4110 as material,the simulation model and geometric model of leaves were improved based on measured data.Firstly,the aboveground morphology data were track-ing recorded,and the feature parameters were extracted.Then the leaf length and leaf shape simulation models were established and improved based on measured data,and good results were obtained.In the end,the leav-es were conducted geometric simulation using NURBS surface technology,the leaf curl and twist models were also achieved.This research would provide technical supports for three -dimensional dynamic modeling of wheat and supply research bases for field management and decision.%以特定品种（偃展4110）小麦为研究对象，基于实测数据，完善了该品种小麦叶片的模拟模型及几何模型。首先，对其地上部的形态特征数据进行跟踪记录，并进行了特征参数提取；然后，基于实测数据进行叶片模拟模型构建，完善了该品种小麦叶片的叶长模拟模型与叶形模拟模型，并取得良好结果；最后，利用NURBS 曲面建模技术对叶片进行几何模拟，并完成了叶片卷曲及扭曲等形变状态。本研究可为小麦三维动态建模提供技术支持，为田间管理与决策提供研究基础。
