基于Bezier曲面的麦穗生长建模研究

Modeling of Wheat Ears Growth Based on Bezier Surface

小麦的生长模拟模型对小麦的生长调控与管理有重要的理论意义和应用价值。以小麦麦穗的抽穗到成熟这一阶段的过程作为研究对象,利用Bezier曲面对小麦的麦粒、外稃和内稃进行了统一建模。对小麦麦穗中的麦粒、外稃和内稃模型进行了重新多边形化,以使其可以更容易检测出麦穗中麦粒的碰撞。该方法可以模拟小麦麦穗的生长过程,具有较高的建模效率。实验结果表明:该方法具有较好的建模效果,能够实现不同生育期的麦穗的建模。

Simulation model of wheat growth has important theoretical significance and application value for wheat growth regulation and management. Study the growth of wheat ears from heading to maturity. We propose an unified modeling method for the grain, lemma and palea of wheat ears based on Bezier surface. Meanwhile, all the models are re-polygonized so that it can be easier to detect the collision. The method can simulate the growth of wheat ear with relatively high modeling efficiency. Experiment results show that the proposed method has very good modeling effect and the modeling of wheat ear at different growth stages can be achieved.
