A model system of virtual plant based on both L-system and image modeling was proposed. The main stem of rice was constructed by L system. And the remainder details of rice were described by the venation model of plant organ surface. In the given prototype system, the controllability of plant growth model was improved by rule-model, reducing the complexity of plant model and enhancing the visual presentation of virtual plat growth. The experiment results showed that the prototype was feasible.%提出了一种结合图像重建和L 系统的虚拟水稻可视化模型系统.水稻主茎采用L系统生成,由于水稻细节对视觉效果影响较小,采用水稻器官表面重建,用规则建模来提高模型的可控性,基于图像重建可以得到更好的可视效果.结果表明,该系统方法能够降低建模复杂度,较好地实现虚拟水稻的可视化展现.
