珍稀植物传粉与保护虚拟仿真教学项目的构建与应用

Construction and Application of Virtual Simulation Teaching System for Pollination and Conservation of Rare Plants

综合利用unity3D、三维数字采集还原、全景摄影、无人机航拍、测绘数字高程模型(DEM)、计算机仿真等先进信息技术,将珍稀兰科植物的形态结构、生境选择、传粉策略和保护管理等核心要素进行虚拟仿真,开发了兰科植物传粉与保护虚拟仿真实验项目。项目呈现手段多样,设置基础理论及核心操作引导,在线帮助和讨论环节,学习的沉浸感、交互性和趣味性强,激发了学生学习兴趣,解决了珍稀濒危植物不易获得、时空因素限制等教学瓶颈问题;增进了学生对以兰科植物为代表的珍稀濒危植物资源与保护的理解,为植物学虚拟仿真教学项目提供了良好范例。

A virtual simulation experiment platform for pollination and habitatprotection of rare orchids was developed by virtual simulation on the core elements of the form structure,habitat selection,pollination strategy and conservation of representative rare orchids with the technologiesof unity 3D,3D digital collection and reduction,panoramic photography,UAV aerial photography,digital elevation model(DEM),computer simulation,etc.The project presented various display types,set up basic theory and core operation guidance as well as online help and discussion system,which stimulates the students’learninginterest due to its high attraction,interactivity and interest.The system hassolved the teaching bottleneck problems such as difficult collection of rare and endangered plants,time and space constraints,and improved the knowledges of conservation of rare and endangered plants represented by orchids.Therefore,the system has provideda good example for the virtual simulation teaching system of botany.
