Design of Virtual Simulation Model System for Engineering Graphics and Mapping and Analysis of Its Teaching Application

针对工科类专业工程测绘课程实验需求,基于云服务、虚拟模型技术和可视化仿真体验,开发了工程测绘虚拟仿真实验系统。该系统对工程测绘实验方案、互动环节和考核评价等内容的教学体系重构和数字化重建,以测绘对象三维建模代替零部件实物,降低实验教学成本投入;以虚拟实验室代替实际测绘实验室,减少实验室资源占用;以在线实验代替固定时间课内实验,提高课程教学灵活度。为校内外师生提供灵活交互、强沉浸感和高用户黏度的在线实验教学服务,驱动学生自主完成实验学习和在线互动等活动,从而使学生的空间思维、图感表达能力得到充分训练,有效提高学生的工程创新素质。

Aiming at the needs of graphics engineering experiment for engineering majors,a virtual simulation experimental system is developed based on cloud technology,virtual modeling and visual simulation.The system reconstructs and digitizes the teaching system of graphics engineering programs.The artificial models are replaced by the visual 3D modeling.The cost of experimental teaching is reduced.Actual mapping laboratories in the teaching building are replaced by virtual laboratories,which reduces the occupation of laboratory and classroom.The fixed-time in-class experiment is replaced by the discrete-time online experiment.The flexibility of course teaching is improved.It can provide online experimental teaching services for teachers and students both at home and abroad with flexible interaction,strong immersion and high user viscosity,which drives students to indepen-dently complete experimental learning,online interaction and homework submission activities,so that students’spatial thinking and graphic expression ability can be fully trained,and the engineering innovation quality of students is effectively improved.
