中草药野外采集仿真实训系统研究

Research on Simulation Training System of Field Collection of Chinese Herbal Medicine

中草药野外采集实训教学,存在生长季节、生长环境限制,还有野兽、毒蛇、毒蜂等危险,针对上述问题,研究了一种中草药野外采集仿真实训的教学方法。采用专业植物建模软件SpeedTree构建野外虚拟植被场景、树形植物、草形植物模型,不仅可以简化植物模型,而且可以构建LOD植物模型,在近距离时观察精细的植物模型,在远距离时观察简化植物模型,不仅实现了高逼真植被模型的创建,而且提高了整个植被场景的实时渲染效率。结合3DsMax拥有大量植物模型库的优势,减少了许多中草药模型的制作量。野外交互实训功能及仿真场景构建,采用Unity3D渲染引擎。在研究中草药野外采集实际流程的基础上,设计了系统功能模块,提出了系统开发方法、开发流程,设计了系统总体结构,开发了中草药野外采集仿真实训原型系统。实验表明,上述实训方法使学生身临其境,调动了学生实训教学的积极性,有助于掌握中草药知识。

Chinese herbal medicine field collection training teaching has the limitations of growth season and growth environment, as well as the dangers of wild animals, poisonous snakes and poisonous bees. In view of the above problems, a teaching method of Chinese herbal medicine field collection simulation training was studied.Using the professional plant modeling software speed Tree to build the field virtual vegetation scene, tree plant and grass plant model can not only simplify the plant model, but also build the LOD plant model. Observe the fine plant model at a close distance and the simplified plant model at a long distance, we not only realized the creation of high realistic vegetation model, but also improved the real-time rendering efficiency of the whole vegetation scene. Combined with the advantage that 3dsmax has a large number of plant model libraries, we reduced the production of many Chinese herbal models. The field interactive training function and simulation scene construction used unity3d rendering engine. Based on the study of the actual process of field collection of Chinese herbal medicine, the system function module was designed, the system development method and process were proposed, the overall structure of the system was designed, and the field plants simulation training prototype system of Chinese herbal medicine was developed.The experiment shows that this training method enables students to be involved in the situation, arouses the enthusiasm of students’ practical teaching, and helps them master the knowledge of Chinese herbal medicine.
