Abstract: 
visual inspection of wheat growth has been a useful tool for understanding and implementing agricultural techniques and a way to accurately predict the growth status of wheat yields for economists and policy decision makers. In this paper, we present a polygonal approach for modeling the growth process of wheat ears. The grain, lemma, and palea of wheat ears are represented as editable polygonal models, which can be re-polygonized to detect collision during the growth process. We then rotate and move the colliding grain to resolve the collision problem. A linear interpolation and a spherical interpolation are developed to simulate the growth of wheat grain, performed in the process of heading and growth of wheat grain. Experimental results show that the method has a good modeling effect and can realize the modeling of wheat ears at different growth stages.

基于多边形的麦穗生长建模

摘要:采用作物建模技术构建小麦仿真模型,对监测小麦生长、分析小麦生长态势等工作有重要意义和价值。针对小麦麦穗的生长过程建模问题,提出一种基于多边形的麦穗生长建模方法。该方法包括麦穗的多边形建模和生长过程插值。首先将麦穗的外稃和内稃表示成可编辑的多边形模型,然后利用球形插值和线性插值建立麦穗的生长过程模型。所设计的球形插值对麦穗中麦粒生长过程中的角度变化进行建模,线性插值对麦穗中麦粒生长过程中的大小变化进行建模。数值仿真结果表明,该方法可建立高效的麦穗生长模型。
