【摘要】：随着网络教学的兴起,虚拟现实技术用于实验教学,成为强化实验室建设、改革实验教学手段的一个重要发展方向。介绍虚拟建模和开发软件,并以我院仿真模拟摄影测量与遥感实验室为原型,采用VRML软件为主,三维建模软件SkecthUP和3Ds Max为辅,阐述系统设计与实现的具体过程,构建虚拟航空摄影测量实验系统。该系统主要包括虚拟地形地貌沙盘(虚拟校园模型和虚拟栅格地形)、虚拟全数字摄影测量工作站模型、虚拟无人机和控制轨道动态模型,以及虚拟实验室场景。具有数字摄影测量工作站动态操作演示、无人飞机航空摄影测量操作演示,以及实验室参观展示等功能。研究成果无实体实验室的时空限制,有利于学生开展自主学习,有效地提高摄影测量实验教学质量,其对于虚拟实验系统的研发具有一定的借鉴意义。
[Abstract]:With the rise of network teaching, the application of virtual reality technology in experimental teaching has become an important development direction to strengthen the construction of laboratory and reform the means of experimental teaching. This paper introduces the virtual modeling and development software, and takes the simulation photogrammetry and remote sensing laboratory of our hospital as the prototype, adopts VRML software as the main software and 3D modeling software SkecthUP and 3Ds Max as the auxiliary, and expounds the concrete process of the system design and implementation. The virtual aerial photogrammetry experimental system is constructed. The system mainly includes virtual terrain and geomorphology sand table (virtual campus model and virtual raster terrain), virtual all-digital photogrammetry workstation model, virtual UAV and control orbit dynamic model, as well as virtual laboratory scene. It has the functions of dynamic operation demonstration of digital photogrammetry workstation, aerial photogrammetry demonstration of unmanned aircraft, and laboratory visit display. The research results have no time and space limitation of physical laboratory, which is helpful for students to carry out autonomous learning and effectively improve the teaching quality of photogrammetry experiment. It has certain reference significance for the research and development of virtual experiment system.
