摘　　要：为了提升高校在线实验教学效果,设计了基于虚拟现实技术的高校在线实验教学平台。该平台采用服务器/客户机分布式体系,服务器端由Web服务器与数据库服务器共同实现平台应用功能,客户端主要负责实现平台虚拟实验教学。在采用虚拟交互模块建立虚拟场景时,主要通过形象建模和几何建模完成立体图形拼接和纹理、光照等处理,利用摄像机运动跟踪算法实现平台全景漫游。应用实例结果表明,该平台可以逼真实现在线实验教学,交互性强,具有较高的实际应用价值。In order to improve the effect of online experiment teaching in colleges and universities,an online experiment teaching platform based on virtual reality technology is designed.The platform adopts distributed server/client structure,and the Web server and database server jointly realize the platform application function.The client is mainly responsible for the platform virtual experiment teaching.When using the virtual interaction module to establish the virtual scene,the three-dimensional graphics splicing and texture,lighting and other processing are mainly completed through image modeling and geometric modeling,and the camera is used.The results of application examples show that the platform can realize online experiment teaching vividly,with strong interaction,and has higher application value in teaching.
